Custom Peptide Synthesis: From Sequence Design to Industrial Scale


We serve as a dedicated technical partner for pharmaceutical research, biotechnology, diagnostic assay development, and vaccine production. We specialize in the synthesis of custom peptides ranging from 2 to 80 amino acids, integrating advanced Solid-Phase Peptide Synthesis (SPPS) with rigorous analytical validation to ensure high sequence accuracy and batch-to-batch consistency.

 

Core Processes and Quality Control

 

Our manufacturing philosophy is built on technical precision, process transparency, and strict adherence to international quality standards:


Synthesis Strategy: We perform a pre-synthesis feasibility evaluation for every sequence. Depending on the sequence characteristics (e.g., hydrophobicity, aggregation propensity, or charge), we dynamically adjust deprotection protocols and coupling reagent ratios. For long or complex sequences, we utilize microwave-assisted synthesis or fragment condensation strategies to minimize deletion products and ensure structural integrity.
Purification and Validation: We utilize preparative HPLC to remove truncated sequences and deletion products. Every batch undergoes mandatory validation via LC-MS or MALDI-TOF MS to confirm molecular weight and sequence accuracy.
Batch Consistency: Our standardized operating procedures (SOPs) and robust quality management systems ensure that performance remains consistent from milligram-scale screening quantities to kilogram-scale production.

FAQ

 

Q: What peptide purity should I choose?

A: Purity requirements depend on your application. Crude peptides are suitable for preliminary screening; ≥95% is the standard for biological research; ≥98% or ≥99% is recommended for high-performance analytical applications or pre-clinical studies.

Q: How is peptide purity verified?

A: All batches are verified via High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). Full analytical documentation is provided with every shipment.

Q: Can you handle difficult or long sequences?

A: Yes. We evaluate each sequence individually. While 2–80 amino acids is our standard range, we utilize specialized fragment condensation strategies for longer or complex sequences to ensure high quality.

Q: Do you provide additional testing?

A: We provide standard CoA, HPLC, and MS reports. Additional testing-including Amino Acid Analysis (AAA), water content, residual solvent analysis, endotoxin levels, and sterility testing-is available upon request.

Q: How do you ensure stability during international shipping?

A: We utilize industry-standard cold-chain logistics, including vacuum packaging and temperature-controlled shipping materials (e.g., dry ice), to maintain structural integrity and prevent degradation during transit to any global location.
