VAP-1, Recombinant, Human (Membrane Primary Amine Oxidase, Copper Amine Oxidase, HPAO, Semicarbazide-sensitive Amine Oxidase, SSAO, Vascular Adhesion Protein 1, AOC3, VAP1)

VAP-1 is a type II membrane cell adhesion protein belonging to the copper/topaquinone oxidase family. It is primarily expressed on the high endothelial venules of peripheral lymph nodes and on hepatic endothelia. VAP-1 can catalyze the oxidative deamination of low molecular weight amines, and plays an important role in the migration of lymphocytes to inflamed tissue. Inhibition of VAP-1 can protect against inflammation related damage to certain injured tissues. Additionally, VAP-1 can function as a significant prognostic marker for certain cancers and cardiovascular diseases. Recombinant VAP-1 is a mixture of monomeric and disulfide linked homodimeric forms of a 737aa polypeptide corresponding to aa27-763 of the VAP-1 precursor.\n\nBiological Activity:\nMeasured by its ability to produce hydrogen peroxide during the oxidation of benzylamine.

For reconstituted solutions of most products, we recommend short-term storage at 4 degrees C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20 degrees C. Additional freeze/thaw cycles may cause some denaturation of the protein.
