  • Immunocytochemistry/ Immunofluorescence 1:1000 - 1:5000
  • Immunohistochemistry Free-Floating
  • Immunohistochemistry 1:1000 - 1:5000
  • Immunohistochemistry-Paraffin
  • Western Blot 1:1000 - 1:5000
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.

Calbindin D28k is a member of a large family of intracellular calcium-binding proteins, containing EF-hand calcium binding motifs, and related to calmodulin and troponin-C. The biological roles of Calbindin D28k include calcium regulation and calcium-dependent signalling in neurons and during development. Decreases in Calbindin D28k abundance, or loss of Calbindin D28k immunoreactivity, is found in models of neurological disorders such as epilepsy, and in neurodegenerative diseases. Calbindin antibody is often used as a marker for cerebellum Purkinje cells.

FAQs for Calbindin D-28K Antibody (NBP2-50028). (Showing 1 - 1 of 1 FAQs).

  1. I am doing research on Neuroscience and I would like to use some antibodies, especially in Western Blots, but I could do other assays: - alpha7 nicotinic cholinergic receptor; - parvalbumin; - calbindin D28K; The preferred reactivity is anti-human and anti-mouse. Do you have these antibodies? Are they in stock? And what about the prizes: How much are they? How much are the shipping costs? Could you make me any offer?
    • This link will take you to all of our alpha7 nicotinic cholingergic receptor antibodies currently available for purchase. Please see the following link for our Calbinin D28K antibodies reactive against mouse and human. We currently do not have any Parvalbumin antibodies that have been tested in mouse. I would like to introduce you to our Innovators Reward Program. Try our primary antibodies in an untested species or application, without the financial risk of failure. The pricing and availability of our products depends on your country.
