The Calbindin D-28K Antibody was raised to Calbindin D-28k purified from bovine cerebellum. The antibody has a proven maximum biotin-streptavidin/HRP staining at a 1/5,000 - 1/10,000 dilution and a 4+ indirect immunofluorescence staining at a 1/500 - 1/1,000 dilution in rat striatum, cortex, and hippocampus. The antiserum has been characterized as specific to calbindin D-28k; please see reference listed below. Optimal dilution will vary depending upon fixation, labeling technique and/or detection system; therefore, a dilution series is recommended.
