Description: Peptide to [Phe13, Tyr19]-MCH (Human, Mouse, Rat) Form: Lyophilized powder CAS Number : 160201-86-5Molecular Formula : C109H160N30O26S4Molecular Weight : 2434.93Purity : > 95%Chemical Structure : Asp-Phe-Asp-Met-Leu-Arg-Cys-Met-Leu-Gly-Arg-Val-Phe-Arg-Pro-Cys-Trp-Gln-Tyr (Disulfide bridge Cys7-Cys16)Application : This derivative suitable for iodination is a further development of natural MCH, which loses its activity upon iodination. The labeled compound enabled to establish the first radioreceptor assay for MCH. Saturation binding experiments with this peptide, radioiodinated, revealed a Bmax of 1090 and a Kd of 1 · 10⁻¹⁰M for receptors in G4F-7 mouse melanoma cells.Storage/Stability : Shipped at 4°C. Store at -20°C for one year.
