Manufacturing & Quality Control

The production of integrative peptides employs solid-phase peptide synthesis (SPPS) using Fmoc chemistry, enabling precise control over amino acid sequence and side-chain protection. This method allows for scalable manufacturing from milligram to kilogram quantities while maintaining sequence fidelity. The process begins with resin loading, followed by sequential deprotection and coupling cycles, each monitored by Kaiser test or HPLC to ensure >99% coupling efficiency. After complete chain assembly, the peptide is cleaved from the resin using TFA-based cocktails, with scavengers to prevent side reactions.

Purification is achieved through preparative reverse-phase HPLC using C18 columns with gradient elution of acetonitrile/water containing 0.1% TFA. Fractions are collected based on UV absorbance at 214 nm and 280 nm, with purity confirmed by analytical HPLC. Lyophilization yields a white to off-white powder with residual moisture below 2%.
