Product Description GenScript BSA ELISA kit (Cat. No. L00944) is a Sandwich ELISA Kit that is designed for quantitative measurement of bovine serum albumin (BSA) in testing samples. These outstanding features make it a great solution for routine BSA impurity detection, quality control and lot release, as well as purification process optimization. 
Most commercial serum-free media are formulated with various biological macromolecules that can replace the function of serum, such as bovine serum albumin (BSA), transferrin, and insulin. The use of serum-free media can greatly reduce the amount of potential impurities, but the final product serving therapeutic purpose should be highly purified and quality controlled. Hence, it is necessary to test for trace media impurities, and the residual concentration of BSA is usually an important indicator for quality control in production.

Assay Principle
Assay Principle BSA ELISA kit utilizes two anti-BSA monoclonal antibodies which bind to different epitopes of BSA. When the sample and the anti-BSA detection antibody conjugated with biotin are added to the plate (Capture Plate) coated with the anti-BSA capture antibody, the capture antibody and the detection antibody (Biotin Anti-BSA Antibody) bind to the BSA in the sample in a sandwich format. Streptavidin-Horseradish Peroxidase conjugate (Streptavidin-HRP) is added to interact with the Biotin Anti-BSA Antibody. After washing steps, 3,3',5,5'-Tetramethylbenzidine solution (TMB Solution) is added resulting in formation of blue color. The reaction is stopped by adding Stop Solution. Application of the Stop Solution results in the color changing from blue to yellow. The intensity of the color can be read at 450 nm and 650 nm by a microplate reader. The quantity of BSA in the sample is precisely quantified against a BSA standard curve.
