Add 5ml Proteinase K Storage Buffer to Proteinase K to dissolve it, and storeit at -20℃. Do not leave the prepared Proteinase K at room temperature for a longtime, and avoid repeated freezing and thawing to avoid affecting its activity.2. Repeated freezing and thawing of the sample should be avoided, as this may resultin smaller DNA fragments and a decrease in the amount of extracted DNA. 3.This kit can extract up to 1-5 ml of whole blood samples, if you need to extracta large number of blood samples, please use the blood genome non-column extractionkit. 4. Anhydrous ethanol should be added to Buffer GW1 and Buffer GW2 according to theinstructions on the label of the reagent bottle before first use.5. Please check Buffer GL for crystallization or precipitation before use, if thereis any crystallization or precipitation, please put it in 56℃water bath to re-dissolve.6. If the downstream experiments are sensitive to RNA contamination, 4µl of DNaseFree RNase A (100mg/ml) can be added, RNase A is not provided in the kit, and canbe ordered separately from our company if needed.7. The Buffer RCL in the kit cannot be used further after turbidity.procedure1. Add 1-5 ml of blood sample to a centrifuge tube (supplied) and add 3 times thevolume of Buffer RCL and gently vortex or invert to mix.2. Centrifuge at 3000 rpm (~900 x g) for 10 minutes and carefully aspirate thesupernatant.3. Add 400 µl Buffer GR to the precipitate and resuspend the precipitate. Note: If the downstream assay is sensitive to RNA, add 4 µl of RNase A (100 mg/ml)solution, shake for 15 seconds, and leave at room temperature for 5 minutes.4. For 1-2 ml blood sample extraction, add 40µl Proteinase K to the above solutionand mix well; for 2-5 ml blood sample extraction, add 100µl Proteinase K to theabove solution and mix well.5. Add 400 µl of Buffer GL, mix upside down 15 times, and vigorously vortex andshake for at least 1 minute. Note: Do not add Proteinase K directly to Buffer GL.6. Incubate at 70°C for 10 minutes, during which time mixing was inverted severaltimes.Note: 1) If the solution is not completely clear, add appropriate amount of Proteinase K and incubate. Extend the incubation time until the solution is completely clear. 2) The yield of DNA has been maximized by 10 minutes of incubation, and continuedprolongation of the incubation time has no effect on DNA yield or purity.7. Add 400 µl of anhydrous ethanol and mix upside down 10 times. Centrifuge brieflyto concentrate the liquid on the walls and cap to the bottom of the tube.8. Add all of the solution obtained in the previous step to the Spin Columns DL inthe collection tube. If the solution cannot be added all at once, transfer it severaltimes. centrifuge at 12,000 rpm (~13,400 x g) for 1 minute, pour off the waste liquidfrom the collection tube, and put the column back into the collection tube.9. Add 500 µl of Buffer GW1 to the adsorption column (check that anhydrous ethanolis added before use), centrifuge at 12,000 rpm for 1 minute, pour off the waste liquidin the collection tube, and put the adsorption column back into the collection tube.Note: It is recommended that step 9 be repeated if the sample being extracted isthe blood genome of a species such as mice or monkeys from which hemoglobin isdifficult to remove.10. Add 500 µl Buffer GW2 to the adsorption column (check that anhydrous ethanolis added before use), centrifuge at 12,000 rpm for 1 minute, pour off the waste liquidin the collection tube, and put the adsorption column back into the collection tube.Note: Step 10 can be repeated if further DNA purity is required.11. Centrifuge at 12,000 rpm for 2 minutes and pour off the waste liquid in thecollection tube. Leave the adsorption column at room temperature for several minutesto dry thoroughly. Note: The purpose of this step is to remove residual ethanol from the adsorptioncolumn, which can interfere with subsequent enzymatic reactions (digestion, PCR,etc.)12. Place the adsorption column in a new centrifuge tube, add 50-200 µl of BufferGE or sterilized water to the middle of the adsorption column overhanging the column,leave it at room temperature for 2-5 minutes, centrifuge at 12,000 rpm for 1 minute,collect the DNA solution, and store the DNA at -20℃.Note: 1) If the downstream experiment is sensitive to pH or EDTA, you can use sterilized water for elution. The pH of the eluent has a great influence on theelution efficiency, if water is used as the eluent should ensure that its pH is7.0-8.5 (you can use NaOH to adjust the pH of the water to this range), and the elutionefficiency is not high when the pH is lower than 7.0.2) Incubation at room temperature for 5 minutes prior to centrifugation increasesyield.3) Re-elution with an additional 50-200 µl Buffer GE or sterilized water can increase the yield.4) If the final concentration of DNA is to be increased, the DNA eluate obtainedin step 12 can be re-spiked onto the adsorbent membrane and centrifuged at 12,000rpm. 1min; if the elution volume is less than 200µl, the final concentration of DNA canbe increased, but the total yield may be reduced. If the amount of DNA is less than1 µg, elution with 50 µl Buffer GE or sterilized water is recommended.5) Because DNA preserved in water is subject to acidic hydrolysis, for long-termstorage, it is recommended that it be eluted with Buffer GE and stored at -20℃...

Since the reverse transcription reagent contains a component that inhibits gDNA Eraser, cDNA can be synthesized directly by reverse transcription of gDNA Eraser-treated samples.The kit is equipped with a new high-efficiency reverse transcription enzyme, HiFiScript, with novel mutation sites that dramatically increase the transcriptional activity of the enzyme, resulting in higher efficiency and yield of cDNA first-strand synthesis. The first strand of cDNA can be synthesized with higher efficiency and yield, and the first strand of cDNA can be synthesized from pg total RNA or mRNA. If the reverse transcription product cDNA is used for downstream fluorescence quantitative detection, the reverse transcription reaction can be completed at 42℃ in 15 minutes. This kit is suitable for the synthesis of first-strand cDNA and subsequent RT-PCR, RT-qPCR, and the construction of full-length cDNA libraries.Product Features1. Rapid genome removal: contains gDNA Eraser for genomic DNA removal, which removes genomic DNA in just 2 minutes.2. Rapid reverse transcription: 15 minutes to obtain fluorescent quantitative PCR template cDNA first strand synthesis.3. High sensitivity: cDNA first strand can be synthesized using pg-level total RNA or mRNA templates.4. Highly efficient reverse transcription: Novel mutation sites dramatically increase enzyme activity, resulting in higher yields of cDNA.matters needing attention1. During operation, RNase contamination should be avoided to prevent RNA degradation or cross-contamination in the experiment. It is recommended that operators wear masks and disposable gloves and change the gloves frequently, and use specialized instruments and consumables.2. The reverse transcription system is prepared and operated on ice to prevent degradation of RNA. Store the kit enzymes at -20ºC as soon as possible after use and try to avoid repeated freezing and thawing.3. The reaction system can be scaled up to a maximum of 1 µg of total RNA in 10 µl of reaction system.4. Primer Mix is prepared by Oligo(dT) and Random primer, and Oligo-dT Primer or Gene Specific Primer can also be used according to the experimental needs.5. If the amount of starting RNA is less than 50ng, it is recommended to add RNAase inhibitor (RNasin).6. For RNA templates with complex secondary structures, it is recommended to incubate the template RNA at 65°C for 5 minutes immediately on ice prior to the manipulation step and centrifuge briefly before proceeding to the next step.UsageThaw template RNA on ice; place kit components on ice immediately after thawing at room temperature. Each solution was mixed by vortexing and shaking before use and briefly centrifuged.I. Genomic DNA removal reactions1. Prepare the reaction system according to the following table on ice in a total volume of 10 µl. To ensure the accuracy of the reaction solution preparation, prepare the premixed system in the amount of reaction number + 2 before dispensing it into each reaction tube and finally adding the RNA sample.Note: 1) If the amount of total RNA is greater than 1µg, scale up the reaction system proportionally. If the amount of starting RNA is less than 50ng, it is recommended to add RNAase inhibitor (RNasin).2. Mix by vortex shaking and centrifuge briefly so that the solution on the walls of the tube collects at the bottom.3. Incubate at 42°C for 2 minutes (this can be extended to 30 minutes for room temperature reactions).4．At the end of the reaction, centrifuge briefly and place on ice to cool.II. Reverse transcription reaction1. Prepare the reaction system on ice according to the following table. In order to ensure the accuracy of the reaction solution configuration, first prepare a premixed solution in the amount of number + 2, and then dispense 10 µl into each reaction tube, take 10 µl of the prepared premixed solution and add it to the reaction tube of step 1 where the de-etching of the genome has been completed.Note: 1) Oligo-dT Primer or Gene Specific Primer can be used according to the needs of the experiment, it is recommended to use 50 pmol of Oligo-dT Primer or 2 pmol of Gene Specific Primer for 20 µl reaction system.2. Mix well and centrifuge briefly so that the solution on the walls of the tube collects at the bottom.3. cDNA synthesis reaction conditions:1) If fluorescent quantitative PCR assay is performed downstream, incubate at 42°C for 15 minutes and 85°C for 5 minutes.2) If downstream for normal PCR assay, incubate at 42°C for 30-50 minutes and 85°C for 5 minutes. Note: For templates with complex secondary structure or high GC content, the reverse transcription temperature can be increased to 50°C to enhance reverse transcription efficiency.4. At the end of the reaction, centrifuge briefly and place on ice before proceeding with subsequent PCR or fluorescence quantitative PCR, or place at -20°C if prolonged storage is required.Note: When performing Real-time PCR reactions, the amount of reverse transcription product added should not exceed 1/10 of the total volume of the PCR reaction...
