Rabbit anti Dynorphin B antibody recognizes dynorphin B, an endogenous opioid peptide, also known as rimorphin with the peptide sequence Tyr-Gly-Gly-Phe-Leu-Arg-Arg-Gln-Phe-Lys-Val-Val-Thr, (YGGFLRRQFKVVT) derived from the sequential cleavage of pro-enkephalin B to form leumorphin which is, in turn cleaved to form dynorphin B (Devi et al. 1985). The cleavage of the dynorphin precursors to form the dynorphin neuropeptides is largely controlled by the serine protease cathepsin L which co-localizes with dynorphins in secretory vesicles of brain cortical neurons (Funkelstein et al. 2010) and prohormone convertase 2, a member of the furin, peptidate S8 family (Schwarzer 2009).

Dynorphin b sequence is well conserved among mammal, avian (Youngren et al. 1993) and reptilian (Goldsmith et al. 1992) species. Rabbit anti Dynorphin b antibody is expected to have a wide species cross reactivity.

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
