| Description | Storage buffer: 10mM Tris HCl, 5mM EDTA, 0.03% Bromophenol Blue, 0.03% Xylene Cyanol, 30% Glycerol, pH7.6Product IntroductionThis product is composed of 9 linear double stranded DNA fragments, stored in a 1xLoading Buffer, with dense bands that require high concentration gel and low voltage Storage buffer: 10mM Tris HCl, 5mM EDTA, 0.03% Bromophenol Blue, 0.03% Xylene Cyanol, 30% Glycerol, pH7.6Product IntroductionThis product is composed of 9 linear double stranded DNA fragments, stored in a 1xLoading Buffer, with dense bands that require high concentration gel and low voltage electrophoresis. It is suitable for accurately confirming the size of DNA fragments. The size range is 50-500bp, which are 50bp, 100bp, 150bp, 200bp, 250bp, 300bp, 350bp, 400bp, and 500bp respectively; 250 bp is the bright band, with a concentration 2.5 times that of other bands; In the 5 ul product, each strip contains about 40 ng, and the highlight strip contains about 100 ng.Usage suggestions1. It is recommended to sample 5 ul and increase the sample size appropriately for wide adhesive holes.2. It is recommended to use 2.5-3.5% Agarose or 5% PAGE gel, voltage 4-10 v/cm, and 0.5xTBE buffer for electrophoresis. Pay attention to replacing the electrophoresis buffer in time and using the newly prepared gel to achieve ideal results.3. Stain with EB or other nucleic acid dyes, and observe the electrophoretic bands under UV light.matters needing attention1. This product has been saved in a 1xLoading Buffer and can be directly used for electrophoresis. It is easy to use and the electrophoresis image is clear.2. When using agarose gel containing EB for electrophoretic detection, the bromophenol blue band can be electrophoretic to about 2/3 of the distance, otherwise the small segment will become dark because EB is separated from DNA.3. The accompanying 5xLoading buffer can be used for sample detection.5x Loading Buffer components:10 mM Tris-HCl，5 mM EDTA， pH7.6， 0.03% bromophenol blue, 0.03% xylene blue, 30% glycerol Product componentD745352Component100 T500TStorageD745352ADNA Ladder (50-500bp)500 µL5× 500 µL-20℃.

Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, Proteinase K is a stable and highly reactive serine protease. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, detergents (SDS), and temperature. In the presence of 0.1-0.5% SDS, proteinase K retains activity and will digest a variety of proteins and nucleases in DNA preparations without compromising the integrity of the isolated DNA.ApplicationUseful for the proteolytic inactivation of nucleases during the isolation of DNA and RNA.Removes endotoxins that bind to cationic proteins such as lysozyme and ribonuclease A.Reported useful for the isolation of hepatic, yeast, and mung bean mitochondriaDetermination of enzyme localization on membranesTreatment of paraffin embedded tissue sections to expose antigen binding sites for antibody labeling.Digestion of proteins from brain tissue samples for prions in Transmissible Spongiform Encephalopathies (TSE) research...

Read More | Product Characteristics UNI-StabilPLUS is a universal stabilizer for the dilution and stabilization of both Horseradish Peroxidase (HRP) and Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enablesProduct Characteristics UNI-StabilPLUS is a universal stabilizer for the dilution and stabilization of both Horseradish Peroxidase (HRP) and Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of pre-diluted, ready-to-use conjugates, minimizing assay errors in dilution. Superior stabilization of HRP and AP conjugated antibodies in low as well as high protein dilutions is seen, when using UNI-StabilPLUS. When tested with AP conjugated antibody stability is seen as follows: • at least 3 years at 2-8 °C • at least 2 years at room temperature • at least 4 weeks at 37 °C When tested with HRP conjugated antibody stability is seen as follows: • at least 2 years at 2-8 °C • at least 1 years at room temperature • at least 2 weeks at 37 °CUNI-StabilPLUS is recommended for the dilution of antibodies directed against rabbit immunoglobulins unlike HRP-StabilPLUS (cat. no. H494387) and Antibody Enhancer (cat. no. A494276).Composition & Properties UNI-StabilPLUS is a ready-to use buffer that appears as an opaque solution. The product is based on a mild acid Tris buffer containing proprietary stabilizing components. UNI-StabilPLUS contains neither BSA, nor other material from bovine serum, no azide, mercury or other toxic components.Working Procedure 1.Make a series of dilutions of the HRP- or AP conjugated protein in UNI-StabilPLUS in order to determine the optimal dilution. 2.Run the assay as usual or store the diluted conjugated protein preferably at 2-8 °C.Tips & Tricks • Avoid using phosphate buffers for AP-conjugated antibody assays. We recommend the use of Tris/HCl, Tween as the washing buffer, instead of a PBS buffer which will reduce signal significantly. • For extended stability of HRP conjugated antibodies, HRP-StabilPLUS (cat. no. H494387) is recommended. Handling & Storage • Store solution at 2-8 °C... Read More |
