Frequently Asked Quesions

What makes Mano-Tri Pharma’s custom peptide synthesis services different?

Our custom peptide synthesis services include advanced solid phase peptide synthesis (SPPS) with high-purity reagents and comprehensive in-house control. We specialize in challenging sequences, long-chain peptides, complicated alterations, and multi-chain structures while maintaining worldwide compliance, consistency, and high yields.

Do you support large-scale manufacturing under your peptide synthesis service?

Yes. Our peptide synthesis service accommodates all production scales, from small R&D batches to kilogram-level commercial output. We provide safe, pure, and regulatory-compliant peptides using GMP-ready procedures, sophisticated chromatography, and tailored purification systems.

Can Mano-Tri Pharma develop custom synthesized peptides with complex modifications?

Absolutely. We specialize in creating custom peptides, such as unnatural amino acids, pegylated compounds, cosmetic peptides, and multi-chain peptide APIs. Each project goes through optimized synthesis, efficient cleavage, and high-performance purification.

How do you ensure purity and consistency in peptides produced through solid phase peptide synthesis?

Our solid phase peptide synthesis workflows are based on ultra-pure Fmoc amino acids, sophisticated peptide resins, optimized chemical cycles, and stringent analytical testing. This enables high recovery rates, low contaminants, and consistent batch performance.

Do you offer peptide analogue libraries for early discovery programs?

Yes. We use solid phase peptide synthesis to create rationally designed analogue libraries, which allow for SAR research, potency optimization, and quick screening. These programs work perfectly with our custom peptide synthesis services.
