Delivering High-Purity Custom Peptides, Precisely to Your Specifications

At Bio-Synthesis, purification is a critical component of our peptide manufacturing process—ensuring optimal yield and exceptional purity. Our experienced chromatographers and process chemists utilize advanced high-pressure liquid chromatography (HPLC) techniques to consistently deliver high-quality peptdes. We provide end-to-end, scientist-to-scientist collaboration—from project planning to final delivery—supporting quantities ranging from micrograms to hundreds of grams. This commitment reflects our customer-first philosophy and dedication to excellence.

Enhanced Purification Solutions

We offer industry-standard purification methods, including HPLC, reverse-phase, and ion-exchange chromatography. Additionally, our team can develop customized in-house protocols tailored to your specific yield and purity requirements.

Anion Exchange HPLC
Reverse Phase HPLC
Reverse phase HPLC is the preferred method for separating peptides based on differences in hydrophobicity. It is especially effective for purifying synthetic peptide, as well as modified peptides and conjugated peptide with hydrophobic moieties such as dyes, biotin, or cholesterol.
Anion Exchange HPLC
Anion exchange chromatography is the one of the mthod for purifying peptides where charge-based separation yields optimal resolution—especially for unmodified sequences. This technique is highly effective for processing large quantities of oligos with simple, non-complex structures, offering both efficiency and high purity.
