The purity of synthetic peptides is a critical factor that directly influences the reproducibility and reliability of your experimental outcomes. Whether for basic research, diagnostics, or therapeutic development, low-quality peptides can lead to inconsistent results, off-target effects, and wasted resources. At GenCefe Biotech, we prioritize high-purity peptides and comprehensive quality control (QC) throughout the synthesis process. 

Why Peptide Purity Matters: 

     ●      Research reproducibility: Impure peptides may contain truncated sequences or side-products that affect biological assays. 

     ●      Assay specificity: Contaminants can interfere with target binding, enzymatic reactions, or cellular uptake. 

     ●      Therapeutic applications: Regulatory requirements demand rigorous purity for clinical-grade peptides. 

How Purity Is Measured: 

     ●      High-Performance Liquid Chromatography (HPLC): Used to quantify purity and identify impurities based on retention times and peak integration. 

     ●      Mass Spectrometry (MS): Confirms the molecular weight and integrity of the synthesized peptide. 

     ●      Capillary Electrophoresis (CE): Offers high-resolution separation of charged peptide species. 

Common Purity Grades: 

     ●      Crude: –50–70% (for initial screening) 

     ●      Desalted: -70–85% 

     ●      90%: Suitable for in vitro assays 

     ●      95%: Required for in vivo research or diagnostic use 

     ●      98%: Pharmaceutical/clinical grade 

GenCefe’s Quality Assurance Process: Our QC protocols include: 

     ●      Real-time monitoring during synthesis 

     ●      HPLC and MS analysis of every batch 

     ●      Custom documentation and COA 

     ●      Optional endotoxin and microbial testing for high-grade peptides 

Customization and Transparency: Customers can request specific purity levels and analytical data. We provide complete transparency in reporting, helping you make informed decisions for your project. 

Conclusion: 

Peptide purity isn't a luxury—it's a necessity. GenCefe ensures your  peptides  meet the highest standards through a blend of advanced technology and expert oversight.
