This Protein A purified antibody has been tested for use in ELISA and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect a predominant band approximately 90-180 kDa in size corresponding to RREB1 by western blotting in the appropriate cell lysate or extract. Multiple bands seen in the above western blot may indicate cross-reactive isoforms or truncated protein products.
