DSIP (Delta Sleep-Inducing Peptide) is supplied by PEPTIDE.Power as a laboratory research reference material for in-vitro and laboratory research use only. The material is a synthetic nonapeptide consisting of nine residues in the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (single-letter: WAGGDASGE), presenting a tryptophan N-terminus and a free glutamic acid C-terminus. Both aspartate and glutamate side chains contribute acidic character to the molecule, while the indole ring of the N-terminal Trp provides a convenient UV chromophore near 280 nm for spectrophotometric identity checks and HPLC detection.<\/p>\n
DSIP is characterized by the molecular formula C35H48N10O15, an average molecular weight of 848.8 g\/mol, and a monoisotopic mass of 848.3301 Da, corresponding to CAS 62568-57-4 and PubChem CID 68816. Additional structural descriptors include the InChIKey ZRZROXNBKJAOKB-GFVHOAGBSA-N and the isomeric SMILES CC(C(=O)NCC(=O)NCC(=O)NC(CC(=O)O)C(=O)NC(C)C(=O)NC(CO)C(=O)NCC(=O)NC(CCC(=O)O)C(=O)O)NC(=O)C(CC1=CNC2=CC=CC=C21)N, which together allow unambiguous cross-referencing across cheminformatics databases and internal LIMS records.<\/p>\n
The material is produced by chemical synthesis and is provided as a white to off-white lyophilized powder at a purity of not less than 98% by HPLC, with lot-specific values, residual solvent notes, and mass-spectrometric identity confirmation reported on the accompanying Certificate of Analysis. The lyophilized physical form supports reconstitution in laboratory-grade aqueous or mixed aqueous-organic systems typical of analytical peptide workflows, and the presence of multiple carboxylate groups makes DSIP amenable to ion-exchange and reversed-phase separation methods.<\/p>\n
Published scientific literature has examined DSIP in preclinical research, and it is commonly used as a comparator, calibration standard, or identity reference in analytical method development, chromatographic system suitability testing, and mass-spectrometric characterization of related peptide sequences. PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding this material and provides no administration or dosing guidance.<\/p>\n
This DSIP reference material is not a drug, supplement, cosmetic, or food, and is not for human or veterinary use, injection, or ingestion. Identity and purity for each lot are documented on the lot-specific Certificate of Analysis, available on request to qualified research purchasers.<\/p>\n","protected":false},"excerpt":{"rendered":"
