无核酸酶白蛋白

牛血清白蛋白（BSA）是一种源自牛的血清白蛋白蛋白。它常用作蛋白质浓度标准品、免疫分析中的封闭剂，以及酶和其他蛋白质的稳定剂。这种无核酸酶的制备物适用于必须避免核酸酶污染的分子生物学应用。

Bovine Serum Albumin (BSA) is a serum albumin protein derived from cows. It is commonly used as a protein concentration standard, as a blocking agent in immunoassays, and as a stabilizer for enzymes and other proteins. This nuclease-free preparation is suitable for molecular biology applications where nuclease contamination must be avoided.
