Rabbit anti Leumorphin antibody recognizes rat leumorphin, also known as dynorphin B29. Leumorphin is a 28 amino acid opioid peptide resulting from cleavage of proenkephalin-B. Leumorphin positive cells are found in the paraventricular, supraoptic nucleus and fibres in the lateral hypothalamus of colchicine treated rat brain (Neal & Newman 1989). Leumorphin has been reported to exert anti-apoptotic effects in rat PC12 pheochromocytoma cells (Lee et al. 2005).

Rabbit anti leumorphin has been used successfully to detect leumorphin in murine brain using immunohistochemistry on cryostat sections.(Zhang et al.2005).
