The process involves: Attachment of the first amino acid (C-terminus) to a solid resin support Deprotection of the alpha-amino group Coupling of the next protected amino acid using coupling reagents (e.g., HBTU, DIC) Washing to remove excess reagents Repetition of steps 24 until the full sequence is assembled Cleavage from the resin and side-chain deprotection Purification via HPLC (High-Performance Liquid Chromatography) Lyophilization to produce the final stable powder Quality control in reputable peptide science laboratories includes: Mass Spectrometry (MS) to verify molecular weight and sequence HPLC purity analysis (typically 98% purity for research-grade compounds) Certificate of Analysis (CoA) documentation for every batch At Ageless Vitality Peptides, we source from manufacturing partners who adhere to these standards, providing researchers with reliable, reproducible compounds for their investigations
