BSA, acetylated (20 mg/mL)

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 20 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, exonuclease, protease, and RNase activity.
