Prostamax (SKU: PROSTAMAX) is supplied as a synthetic tetrapeptide reference material for laboratory analytical and characterization work. It is provided as a white to off-white lyophilized powder corresponding to the sequence Lys-Glu-Asp-Pro (KEDP, 4 residues), a short peptide of the Khavinson peptide bioregulator class.
The molecular formula is C20H33N5O9, with an average molecular weight of approximately 487.5 g/mol and a monoisotopic mass of 487.228 Da. The expected [M+H]+ ion is 488.235, which supports identity confirmation by LC-MS and high-resolution mass spectrometry. The sequence contains ionizable side chains from lysine (basic) and glutamic and aspartic acids (acidic), giving a zwitterionic character that influences retention on reversed-phase HPLC and selection of ion-pairing additives. The Asp-Pro peptide bond is known to be labile under acidic conditions, a feature that is relevant when choosing mobile-phase pH, sample diluents and storage handling for analytical runs. The PubChem CID is 9848296.
Purity is specified as not less than 98% by HPLC, and a lot-specific Certificate of Analysis documenting chromatographic purity and mass-spectrometric identity is available on request.
