Thermo Fisher, AM2616, UltraPure™ BSA (50 mg/mL), 1 x 50 mg

UltraPure non-acetylated bovine serum albumin is a high-purity protein solution used as a stabilizer, carrier or blocking agent in molecular biology workflows. The preparation contains BSA at 50 mg/mL and is supplied as a single tube holding 50 mg total protein, corresponding to 1 mL of solution. Its non-acetylated formulation avoids chemical acetylation of the protein and is purified for use where DNA or RNA integrity is important. Quality testing addresses contaminating DNase, RNase, endonuclease and protease activities. UltraPure BSA can support PCR, restriction digests, ligations, gel shift assays and blotting applications when the specific protocol calls for a protein additive. The protein may reduce adsorption losses or stabilize sensitive enzymes, but the optimum working concentration depends on reaction chemistry. Dilute using compatible molecular biology-grade buffer and avoid repeated contamination during handling. Store at −20 °C, avoiding a frost-free freezer when possible. This is a liquid BSA reagent, not a powdered 50 mg bottle.
