Orexin A is active biological orexigenic peptide composed of 33 amino acids. It and Orexin B were derived from the same precursor peptide (131 amino acids) by proteolytic processing and are highly specifically localized in neurons located in the lateral hypothalamic area, a region classically implicated in feeding behavior. Both neuropeptides have no significant structural similarities to known families of regulatory peptides. They plays a central role in the integrated control of feeding and energy homeostasis.

The antibody is able to bind to immunized peptide, but not other unrelated peptides in ELISA. It also specifically detects cellular protein derived from selected cell lines. This antibody shows no crossreactivity with other unrelated protein.

Always prepare single-use aliquots planning use while receiving package. A small amount of antibody can be kept at 4°C for daily use. For a long storage, recommend to keep them at -20°C after adding an equal volume of glycerol in PBS. It will not lose activity over a year. Minimize freezing and thawing when use.
