  • Relevance
    CGRP is present in C-cells of the thyroid and in central and peripheral nerves. CGRP has several important physiologic roles: it is a potent vasodilator, and can affect the force and rate of heart beat; it can modulate acetylcholine receptor function at the neuromuscular junction; it has been demonstrated to block tolerance to morphine; and it can modulate antigen presentation in Langerhans cells in the skin. Despite these important physiologic functions, therapeutic strategies using CGRP have been impeded due to the lack of a cloned CGRP receptor with which ligands could be developed.

Thank you for contacting us. We have several antibodies capable of detecting both alpha and beta CGRP, but none appear likely to be able to distinguish between alpha and beta, judging from the immunogens they are raised against. The immunogens are either amino acid sequences that are present in both alpha and beta, or full-length CGRP that is not characterized as alpha or beta. Some of the immunogen sequences are more conserved in one than the other, but there is no data to suggest that the antibody has specificity for one to the exclusion of the other. For example, a BLAST search of the immunogen used to generate ab14180 shows that it is derived from human CGRP beta, but it has 91% identity with human CGRP alpha. It is likely that the antibody recognizes both, but this has not been confirmed. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. I have examined each of the antibodies against one another with respect to your application of ICC in murine cells. ab10987 is a monoclonal antiserum that recognizes 10 amino acids in the C-terminus and recognizes human, rat and dog. I have performed a basic alignment and found that rat and mouse share a C-terminal sequence of GSSVTAQKRSCNTATCVTHRLAGLLSRSGGVVKDNFVPTNVGSEAFGRRRRDLQA compromising 100% identity in the terminal 55 amino acid residues. Therefore this antibody is very likely to cross react against murine CGRP. It has also been applied by ICC. ab22560 and ab14180 both share 96% identity overall and 89% identity of the epitope respectively when compared with the mouse amino acid sequence. These antisera are both polyclonal however and more likely to work given the accommodating nature of polyclonal antisera. However, they have not been applied using ICC. Given the identity in sequence between mouse and rat at the C-terminus and the fact that it has been tested by ICC, in my opinion ab10987 is your best option. As discussed on the telephone I would like to offer you a discount given that abcam can expand the species cross reactivity of this antibody on our datasheet, should you obtain favourable results. Please leave an Abreview by navigating to the antibody at abcam.com and clicking on the Abreview tab. I will follow this up in three months so we can determine how you got on. Please quote reference 30160 when you place the order to receive your discount.
