Background of Calbindin D-28K

Calbindin is a calcium-binding protein belonging to the troponin C superfamily. Calretinin is expressed in central and peripheral nervous system and in many normal and pathological tissues. The rat and human calretinin exhibit 98% sequence homology and 91% homology to many other species. Two calcium binding proteins, calbindin and calretinin, have been reported to be expressed in abundance in Purkinje cells and other cell types in the cerebellum.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence and ELISA with known positive and negative samples to ensure specificity and high affinity.

Our lab used your anti-Calbindin/CALB1 antibody for Flow Cytometry on caudate nucleus a few months ago. I am using mouse, and I plan to use the antibody for IHC next. I am interested in examining caudate nucleus as well as kidney lung in our next experiment. Could you please give me some suggestion on which antibody would work the best for IHC?

Asked: 2019-05-20


I have checked the website and datasheets of our anti-Calbindin/CALB1 antibody and it seems that PB9045 has been validated on mouse in both Flow Cytometry and IHC. Thus PB9045 should work for your application. Our Boster satisfaction guarantee will cover this product for IHC in mouse even if the specific tissue type has not been validated. We do have a comprehensive range of products for IHC detection and you can check out our website to find out more information about them.

From literature amygdala does express CALB1. From, CALB1 is expressed in caudate nucleus, brain, amygdala, cerebellum substantia nigra, kidney lung, among other tissues. Regarding which tissues have CALB1 expression, here are a few articles citing expression in various tissues:
Amygdala, Cerebellum, and Substantia nigra, Pubmed ID: 14702039
Brain, Pubmed ID: 2565876, 3691519

We are currently using anti-Calbindin/CALB1 antibody PB9045 for human tissue, and we are happy with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it true that the antibody can work on bovine tissues as well?

A. Thomas

Asked: 2015-11-25


The anti-Calbindin/CALB1 antibody (PB9045) has not been tested for cross reactivity specifically with bovine tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in bovine you can get your next antibody for free. Please contact me if I can help you with anything.
