Proteinase K from the fungus Engyodontium album is a non-specific serine protease that is useful for general digestion of proteins. Proteinase K Remains Active: • Over a wide pH range (optimal activity between 6.5 and 9.5) • Under denaturing conditions (e.g. the presence of SDS or urea) • In the presence of metal chelating agents (e.g. EDTA) • At comparatively high temperatures (optimum digestion temperature is 65°C) Applications: Removal of endogenous nucleases during the preparation of DNA and RNA; preparation of tissue sections for in situ hybridization. Performance and Quality Testing: End...

Ambion® Acetylated BSA is used as a carrier protein and as an enzyme stabilizer in which the absence of contaminants such as nucleases and proteases is essential. Six tubes of 25 mg are provided, at a concentration of 40–50 mg/mL. The acetylation process inactivates any trace nuclease activity that might be present. While the acetylation process does change BSA's binding characteristics and makes it inhibitory in PCR reactions, it is routinely added to restriction digests. The molecular weight is ~66 kD. Acetylated BSA is rigorously tested for contaminating nonspecific endonuclease, exonucleas...

Ambion® Ultrapure BSA is a "non-acetylated" BSA pure enough to use when DNA or RNA integrity is critical. One tube containing 50 mg is provided, at a concentration of 50 mg/mL. Bovine Serum Albumin (BSA) has many uses as a carrier protein and as a stabilizing agent in enzymatic reactions. In northern, Southern, and dot blot hybridizations, BSA is also used as a blocking agent. It is recommended in buffers for nick translation, polymerase reactions, and ligations. BSA is also a common additive for PCR amplifications, footprinting, and gel shift assays. In restriction digests, BSA has been shown...
