| Application Notes | In Western blot, this antibody recognizes a clear band at ~28 kDa in rat brain lysates which represents Calbindin and it reacts only with Calbindin protein, and not other calcium-binding proteins. A band maybe seen at ~60 kDa and is most likely the dimer of Calbindin. ICC/IF reported from a verified customer review. Use in Immunohistochemistry-paraffin reported in scientific literature (PMID: 29208685). |

| Theoretical MW | 28 kDa. Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors. |
