Functional Peptide Custom Synthesis: Precision Engineered for Biological Activity
Functional peptides are designed to deliver defined biological functions through precise amino acid sequences. We provide end-to-end custom peptide synthesis-from milligram-scale feasibility studies to kilogram-scale commercial production-for drug discovery, diagnostic assays, biomaterial engineering, and beyond.
Core Technical Advantages: Beyond Accuracy
Synthesis is only the start; we prioritize the preservation of biological function through rigorous process control:
Process Monitoring: We monitor deprotection efficiency during every coupling step. By dynamically adjusting coupling conditions, we minimize the accumulation of deletion sequences.
Function-Driven Strategy: Before synthesis, our chemists evaluate amino acid composition and functional domains to optimize the synthetic route, ensuring the final peptide maintains its intended biological activity.
Handling "Difficult" Sequences: For sequences prone to aggregation or poor solubility, we utilize advanced techniques such as double coupling, pseudoproline derivatives, and microwave-assisted synthesis. We also apply tailored solvent systems (e.g., HFIP or NMP) and custom cleavage protocols to maintain purity where standard methods fail.
Modification & Labeling Capabilities
We provide structural modifications to enhance stability, targeting, and detectability:
Labels & Tags: Fluorescent dyes (FITC, Cy3, Cy5, TAMRA), Biotinylation, and stable isotope labeling.
Structural Stability: PEGylation, lipid modification, site-specific cyclization, and stapled peptides.
Chemical Modifications: Phosphorylation, glycosylation, D-amino acid substitution, and multi-site conjugation.
Verification: All modifications are confirmed via LC-MS and High-Resolution Mass Spectrometry (HRMS) to ensure molecular identity.
Rigorous Quality Standards & Analytics
We move beyond generic "high quality" claims by providing transparent, actionable data:
Purity Levels: Research Grade (95%) and High Purity (≥98%) available.
Analytical Suite: Every batch is verified via RP-HPLC and LC-MS/HRMS.
Documentation: Deliverables include a comprehensive Certificate of Analysis (COA) with raw HPLC chromatograms and mass spectra.
Extended QC: Optional services include Amino Acid Analysis (AAA), residual solvent testing, and endotoxin testing for critical biological applications.
