Bovine Serum Albumin, BSA (30% in 0.85% NaCl)

30% Bovine Serum Albumin (BSA) in 0.85% saline is a concentrated stock solution that allows convenient dilution to desired working concentration. BSA is a widely used protein in molecular biology workflows, providing blocking, stabilization, media supplementation, and other key properties to research workflows. Commonly used for blocking applications in immunoassays, along with enzyme and antibody stabilization. In addition, BSA solutions are key in cell and tissue research as a supplement for culture media, with 0.85% saline providing isotonicity.
