Calreticulin is a multifunctional, highly conserved Ca2+ -binding protein that is localized to the endoplasmic reticulum (ER). It is also a molecular chaperone and is involved in protein folding events in the ER. Calreticulin has also been shown to interact with the cytoskeleton and to be involved in the regulation of gene expression. Calreticulin may play a role in cellular proliferation including its apparent activity in the proliferation of certain viruses within mammalian host cells. (2-3) Recently it has been shown that calreticulin is induced in response to various types of cell stress including amino acid deprivation. (1) Close interconnections among protein synthesis, gene expression and calcium signaling have been observed by many researchers in recent years. Calreticulin might be centrally located and crucially participate in the coordination of these functions by the cell.(2-3)

FAQs for Calreticulin Antibody (NB600-101). (Showing 1 - 2 of 2 FAQs).

  1. We are looking to buy an anti-calreticulin antibody that would work for WB and IP. Your reference NB 600-101 wouls correspond, but we need it to work on proteins with altered C terminus. Could you please let us know whether the immunizing peptide for this antibody is located N-terminal to AA #364?
    • Yes, our product NB600-101 was raised against an immunogen that falls between amino acids 150-350 of the mouse Calreticulin protein.
  2. I would like to know how the NB600-101 Calreticulin Antibody was used in the neutralization/blocking application. Do you have protocol details for a particular cell type etc?
    • NB600-101 was validated for B/N via a publication. We do not have a specific protocol available; however, I do have the link to that publication that your customer may find helpful. NCBI site
