Q: I have following question about antibodies against Chromogranin A. Your products list the species but canine is not included. Does it mean that the products cannot be used on canine tissues?

A: When we do not list a species, it means we have not tested an antibody to work with those samples. If we test an antibody and find that it does not work, we will list the species with a minus sign. Unfortunately, we haven't tried these abs on canine tissues and they may work, but we cannot guarantee it. If you would like to purchase one to try, you will be eligible for the Innovators Reward Program.

Background: Chromogranin A

Vasostatin 2 is the N-terminal fragment (19-131 aa) derived from the cleavage of chromogranin A (CgA) which is a member of the chromogranin/secretogranin(granins) family of neuroendocrine secretory proteins. Vasostatin 2 has been shown to exert several biological activities on several tissues and organs and exerts a large spectrum of homeostatic actions, including antifungal and antimicrobial effect, modulation of cell adhesion, and inhibition of parathyroid hormone secretion. Recombinant human Vasostatin 2 protein was expressed in E.coli and purified by using conventional chromatography techniques.
