Bovine Serum Albumin
Bovine Serum Albumin (BSA), often referred to as Fraction V, is a highly versatile protein derived from bovine blood plasma. Its widespread use stems from its consistent quality, cost-effectiveness, and diverse functionalities that support a multitude of scientific applications. BSA is essential in various biochemical experiments, acting as a reliable protein concentration standard and a crucial blocking agent.
- As a reliable protein concentration standard, BSA provides a benchmark for quantifying protein levels in experiments, ensuring accurate results in assays like the Bradford protein assay.
- Its efficacy as a blocking agent is vital in techniques such as ELISA and immunohistochemistry, where it minimizes non-specific binding of antibodies, thereby enhancing signal specificity and reducing background noise.
- In cell and microbial culture, BSA serves as a valuable nutrient, supporting cell growth and viability, particularly in serum-free media formulations.
- BSA also plays a critical role in molecular biology applications by stabilizing enzymes during DNA restriction digests, preventing enzyme adhesion to reaction vessels and ensuring optimal enzymatic activity.
