Built on peptide-specific quality control at every critical stage
Each project begins with an IC-PEPTIDE sequence-specific feasibility assessment covering peptide length, residue composition, hydrophobicity, aggregation risk, protecting-group strategy, and expected purification complexity before production is authorized.
At IC-PEPTIDE, peptide assembly is performed under tightly controlled manufacturing conditions with monitored coupling cycles, reagent traceability, process documentation, and in-process checkpoints to reduce sequence failure, deletion impurities, and batch deviation risk.
Crude material is advanced through purification workflows selected by IC-PEPTIDE for the peptide profile, followed by carefully controlled lyophilization and handling steps to preserve purity, appearance, stability, and delivery format consistency.
Every batch is analytically verified by IC-PEPTIDE using high-performance liquid chromatography (HPLC) and mass spectrometry (MS). Each order is supplied with a detailed Certificate of Analysis (CoA), including mass spectrometry data and purity reporting for batch-specific traceability and release confidence.
