Description: Peptide to Orexin B, Human Form: Lyophilized powder Alternative Names: Hypocretin-2 (human)CAS Number : 205640-91-1Molecular Formula : C123H212N44O35SMolecular Weight : 2899.4Purity : > 95%Chemical Structure : Arg-Ser-Gly-Pro-Pro-Gly-Leu-Gln-Gly-Arg-Leu-Gln-Arg-Leu-Leu-Gln-Ala-Ser-Gly-Asn-His-Ala-Ala-Gly-Ile-Leu-Thr-Met-NH2Application : Like orexin A, orexin B is a hypothalamic neuropeptide regulating the feeding behavior. Central administration of orexin B to rats stimulated food consumption in a similar manner to orexin A, but the effect did not last as long as that of orexin A. The affinity of orexin B for the OX₁ receptor is significantly lower (IC₅₀ = 240 nM) than that of orexin A. Binding affinities for the OX₂ receptor are similar for orexin A and B (IC₅₀ = 38 nM and 36 nM, respectively, for displacement of radiolabeled orexin A bound to the receptor).Storage/Stability : Shipped at 4°C. Store at -20°C for one year.
