What is the difference between BSA-free and BSA-containing RGS-His Antibody?
BSA stabilizes the RGS-His Antibody. We recommend to use the BSA-containing RGS-His Antibody for all standard procedures like dot blots, western blots, etc.. In cases where BSA may interfere with the application, e.g. coupling reactions, the RGS-His Antibody, BSA-free is recommended.
The Tetra-His and Penta-His Antibodies are stable without BSA, and therefore are only offered BSA-free.
