Peptide Easy Clean – Because Time Matters

Peptides represent a powerful class of drugs due to their low toxicity, good tolerability, high selectivity, and high potency. However, the identification and validation of novel peptide drug leads is time- and cost-consuming as it requires high-throughput manufacturing of peptide libraries (N > 24) with solid-phase peptide synthesis (SPPS). Here, the absence of by-products and other impurities is vital for reliable assay results. However, because individual synthesis optimizations are cumbersome and parallel purification with high-pressure liquid chromatography (HPLC) is not feasible, developers often waste enormous time and resources manufacturing and purifying their most promising lead compounds, or low-purity crude peptides are used which might lead to false-negative or false-positive results.

Belyntic overcomes this bottleneck by customization of the Peptide Easy Clean (PEC) purification technology to a 96 well-plate format.

We are focusing on efficacy and are aiming to shorten the development and production times for the ideal therapeutic or diagnostic agent, regardless of its complexity. Belyntic’s PEC technology can support the customer’s activities along the entire value chain of pharmaceutical development and production – from delivering purified peptide libraries for drug discovery, to sophisticated modifications for lead optimization, to economically and ecologically efficient large-scale manufacturing.

The PEC technology allows:

• Fast drug research and screening through first-in-class parallel and automated purification.
• Efficient lead development using sophisticated chemistry to form complex and modified peptides.
• Seamless scalability in volume and number with less time- and solvent-consumption.

In addition, Belyntic’s experienced technical team in Germany can perform feasibility and optimization studies for specific peptide projects. Get in contact for more information, we are pleased to support you and your research!
