| Description | Cell viability and cytotoxicity assays are usually used for drug screening and compound cytotoxicity testing. The CCK-8 kit uses highly water-soluble tetrazolium salt ( called WST-8 ) to produce water-soluble WST-8 for cell proliferation and cytotoxicity assays. Unlike MTT, WST-8 and WST-8 have no Cell viability and cytotoxicity assays are usually used for drug screening and compound cytotoxicity testing. The CCK-8 kit uses highly water-soluble tetrazolium salt ( called WST-8 ) to produce water-soluble WST-8 for cell proliferation and cytotoxicity assays. Unlike MTT, WST-8 and WST-8 have no cytotoxicity in cell culture medium, so multiple downstream experiments can be performed using the same detection plate. CCK-8 method is a convenient colorimetric method for the determination of cell viability. It does not need the solubilization process and only needs the least steps to provide the results. The CCK-8 method can be used for the determination of 96-well microplates and high-throughput screening of 384-well microplates. Advantage：At present, the commercially available liquid CCK-8 kits generally have defects such as harsh storage conditions ( -4C or -20 ), unstable use in different pH ranges, and easy deterioration ( discoloration or precipitation ). The solid instant CCK-8 kit adopts a new formula and Swiss process, which overcomes these shortcomings of the liquid CCK-8 kit. It can be stored at room temperature for a long time ( > 3 years ), ready to use, stable in a wide pH range, and the experimental results are more reliable. Compared with the liquid CCK-8 kit, the solid-soluble CCK-8 kit has higher sensitivity and the biological response time is shortened by half.Application scope:It can be used for drug screening, cell proliferation assay, cytotoxicity assay, tumor drug sensitivity test and activity detection of biological factors. Operating instructions:This reagent kit can be used for drug screening, cell proliferation assay, cytotoxicity assay, tumor drug sensitivity assay, and activity detection of biological factors.1. Carefully and slowly tear along the gap in the packaging bag;2. Pour all the powder in the bag into a clean container containing 10mL of ultrapure water, shake continuously for 1 minute, and use it when the solid is completely dissolved;3. Unused reagents must be stored at low temperatures below 4 ℃.Equipment required for testing:Enzyme reader 96 well plate with 450-490 nm filter;Carbon dioxide incubator;96 well plate, sterilized transparent plate for cell detection;Multi channel pipette (8 or 12 channels: 10-100 µ l);Blood cell counter or cell counter.Cell viability testing:1. Inoculate cell suspension (100 µ l/well) into a 96 well plate and pre culture the plate in a carbon dioxide incubator for 24 hours (37 ℃, 5% CO2);2. Add 10 µ l of CCK-8 solution to each well (be careful not to generate bubbles in the well as it may affect the reading of OD value);3. Incubate the culture plate in the incubator for 1-4 hours;4. Measure the absorbance at 450 nm using an enzyme-linked immunosorbent assay (ELISA) reader;5. If the OD value is not determined temporarily, 10 µ l of 0.1M HCI solution or 1% w/v SDS solution can be added to each well, and the culture plate can be covered and stored in the dark at room temperature. Within 24 hours of measurement, the absorbance will not change.Cell proliferation toxicity testing:1. Inoculate cell suspension (100 µ l/well) into a 96 well plate and pre culture the plate in an incubator for 24 hours (37 ℃, 5% CO2);2. Add 10ul of different concentrations of the substance to be tested to the culture plate;3. Incubate the culture plate in the incubator for an appropriate period of time (e.g. 6, 12, 24, or 48 hours);4. Add 10 µ l of CCK-8 solution to each well (be careful not to generate bubbles in the well as they may affect the reading of the OD value);5. Incubate the culture plate in the incubator for 1-4 hours;6. Measure the absorbance at 450nm using an enzyme-linked immunosorbent assay (ELISA) reader;7. If the OD value is not determined temporarily, 10 µ l of 0.1M HCI solution or 1% w/v SDS solution can be added to each well, and the culture plate can be covered and stored in the dark at room temperature. Within 24 hours of measurement, the absorbance will not change.Calculation method for cell survival rate/inhibition rate:Cell survival rate=[As Ab)/(Ac Ab)] x 100%Inhibition rate=[(Ac As)/(Ac Ab)] x 100%As: absorbance of experimental wells (including cells, culture medium, CCK-8 solution, and drug solution);Ac: absorbance of control wells (including cells, culture medium, CCK-8 solution, without drugs);Ab: Blank well absorbance (including culture medium and CCK-8 solution, excluding cells and drugs).Points for attention： 1.Unused reagents must be stored at low temperature below 4 °C, and stored in the dark at-20 °C for two years after unpacking, so as to avoid repeated thawing ; 2.The culture time of CCK-8 is generally 1-4 hours, but the naked eye can be taken out to observe the color degree in about 30 minutes. According to the cell type, the conditions need to be explored. The best reaction time of CCK-8 is based on the best time of specific color development.3. It is recommended to do a few holes to explore the number of inoculated cells and the culture time after adding CCK-8 reagent ; 3.The WST-8 in this kit will react with reducing agents ( such as some antioxidants ) to interfere with the detection. Before the cell proliferation-toxicity test, the background OD can be checked to confirm whether there is a reducing agent in the substance to be tested. If the effect of reducing agent needs to be removed, the fresh medium can be replaced before adding CCK-8 ( remove the medium, wash the cells twice with the medium, and then add the new medium ) ; 4.Phenol red in the medium does not affect the experimental results, and the absorbance of phenol red can be eliminated by deducting the absorbance of the background in the blank hole during calculation, so it will not affect the detection. 5.It is recommended to use a multi-channel pipette to reduce the difference between parallel holes. When adding CCK-8 reagent, it is recommended to add it obliquely to the wall of the culture plate, not to insert it under the liquid surface of the medium, which is easy to produce bubbles and interfere with OD determination. 6.If the drug contains metal, it has an effect on the color of CCK-8. The final concentration of 1mM lead chloride, ferric chloride and copper sulfate will inhibit the color reaction of 5 %, 15 % and 90 %, and reduce the sensitivity. If the final concentration is 10mM, the color reaction will be 100 % inhibited ; 7.When using a 96-well plate for detection, if the cell culture time is long, attention should be paid to the evaporation problem. On the one hand, because a circle around the 96-well plate is the easiest to evaporate, the method of discarding the surrounding circle can be adopted, and the same amount of PBS, water or culture medium can be added. On the other hand, the 96-well plate can be placed near the water source in the incubator to alleviate evaporation ; 8.When using standard 96-well plates, the minimum inoculation amount of adherent cells is at least 1,000 cells / well ( 100µl medium ). The sensitivity of detecting white blood cells is relatively low, so it is recommended that the inoculation amount should not be less than 2,500 cells / well ( 100 µl medium ). If you want to use a 24-well plate or a 6-well plate experiment, first calculate the corresponding inoculation amount per well, and add the CCK-8 solution according to 10 % of the total volume of the medium per well ; 9.Cell culture time varies according to the type and number of cells ( per well ), usually the color of white blood cells is weak, requiring a longer culture time ( 4 hours ) and a large number of cells ( ~ 105 cells / well ) ; 10.CCK-8 reagent is very low toxic to cells. The continuous reaction between it and dehydrogenase in living cells makes the color of the solution deepen and the OD value increase. The following methods can terminate the CCK-8 reaction ( 96-well plate ) : a ) After the color reaction, the culture plate was placed in a refrigerator at 4 ° C ; b ) 10µL 0.1MHCL solution was added to each well ; c ) 10 µL 1 % ( w / v ) SDS ( sodium dodecyl sulfate ) solution was added to each well. After the reaction stopped, the OD value should be measured within 24 hours. 11.To determine the specific number of cells, it is recommended to do the standard curve at the same time...

One can choose to use the three enzymes in combination to completely remove all N-linked glycans present on a glycoprotein or peptide,The Endo F Multi-Kit will deglycosylate N-linked glycans in both native and denatured conditions. Each enzyme has a distinct specificity for N-linked glycan release. One can choose to use the three enzymes in combination to completely remove all N-linked glycans present on a glycoprotein or peptide, or to use each enzyme independently and thereby determine the type of N-glycans present.Product DescriptionThe Endo F Multi-kit is recommended to deglycosylate native proteins that are resistant to PNGase F cleavage under non-denatured conditions due to the glycan location within the protein’s three-dimensional structure, as these enzymes are known to be less sensitive to protein conformation.Each of the enzymes has a different N-linked glycan specificity:Endoglycosidase F1 cleaves high mannose and some hybrid type N-glycansEndoglycosidase F2 releases biantennary and high mannose glycans (at a 40X reduced rate)Endoglycosidase F3 will release triantennarry and fucosylated biantennary N-glycansContents1 vial: Endo F1- 20 µl (0.3 U)20 mM Tris-HCl pH 7.51 vial: Endo F2- 20 µl (0.1 U)10 mM sodium acetate, 25 mM NaCl, pH 4.51 vial: Endo F3- 20 µl (0.1 U)20 mM Tris-HCl pH 7.51 vial: 5x Reaction Buffer - 400 µl250 mM sodium acetate, pH4.51 vial: 5x Reaction Buffer - 400 µl250 mM sodium phosphate, pH5.5Specific ActivityDefined as the amount of enzyme required to catalyze the release of N-linked oligosaccharides from 1 micro-mole of denatured Ribonuclease B (Endo F1) or porcine fibrinogen peptides (Endo F2/F3) in 1 minute at 37°C, pH 5.5 (PH 4.5 for Endo F3). Cleavage is monitored by SDS-PAGE.FormulationThe enzymes are provided as a sterile-filtered solution.StabilitySeveral days exposure to ambient temperatures will not reduce activity. Stable at least 12 months when stored properly.SpecificityEndo F1 cleaves Asparagine-linked (N-linked) high mannose or hybrid oligosaccharides. Endo F2 cleaves N-linked biantennary oligosaccharides and high mannose (at a 40X reduced rate). Endo F3 cleaves free or N-linked fucosylated biantennary or triantennary oligosaccharides,as well as triamannosylchitobiose core structures. These enzymes cleave between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. The recombinant version is not glycosylated, which may result in properties differing from the native protein.Quality & PurityEndo F1, Endo F2, and Endo F3 are tested for contaminating protease as follows: 10 µg of denatured BSA is incubated at 37°C for 24 hours with 2 µl of enzyme. SDS-PAGE analysis of the treated BSA shows no evidence of degradation. The absence of exoglycosidase contaminants is confirmed by extended incubations with the corresponding pNP-glycosides. Directions for use 1. Add up to 200 µg of glycoprotein to an Eppendorf tube. Adjust to 34 µl final volume with de-ionized water. 2. Add 10 µl Endo F2 &F3 5x Reaction Buffer, 250 mM sodium acetate pH 4.5. Use Endo F1 buffer, 250 mM sodium phosphate pH 5.5 if you are using the Endo F1 enzyme alone. 4. Add 2.0 µl of each enzyme to the reaction. Incubate 3 hours at 37°C. Monitor cleavage by SDS-PAGE.

PCR reaction system Attention: (1) Usually, the final primer concentration of 0.2 µM can get better results, and 0.1-1.0 µM can be used as a reference for setting the range. If the amplification efficiency is not high, the concentration of primer can be increased; if non-specific reaction occurs, the concentration of primer can be decreased to optimize the reaction system.(2) The final concentration of the probe used is related to the fluorescence quantitative PCR instrument used, the type of probe, and the type of fluorescent labeling substance, please refer to the instrument manual or the specific requirements for the use of each fluorescent probe to adjust the concentration.3) Because templates from different species contain different numbers of copies of the target gene, the template can be diluted in a gradient to determine the optimal amount of template to usePCR reaction conditionsmovetemptimingcirculatereverse transcription55°C1 min1premutability95°C10s1)1denaturation95°C1 s40-45Annealing/Extension55-60°C2)10-15s3)40-45Attention: (1) The enzyme used in this product is activated under the condition of pre-denaturation at 95℃ for 30s. Under this condition, most of the templates can be well unchained. For templates with high GC content and complex secondary structure, the pre-denaturation time can be extended to 1min, so as to make the starting template fully unchained, and if the high temperature treatment time is too long, it will affect the activity of the enzyme; for simple templates, pre-denaturation time of 1-10s can also be used, and the optimal pre-denaturation time can be determined according to the template situation.(2) It is recommended to use two-step PCR reaction program, the annealing temperature should be 55-60℃ as the reference range, and the annealing temperature can be increased when non-specific reaction occurs. If you can't get good results due to the use of primers with low Tm values or long amplification products, you can try three-step PCR amplification.3) Whether the actual Real Time PCR instrument used supports rapid amplification cycles, please perform a pre-experiment to verify this for the first attempt...
