Let's talk about Peptide Purity

The purity of a peptide significantly influences the outcomes of a research project, making peptide purity analysis a common practice in diverse industries. Impurities in peptide products can derive from the chemical synthesis process, the culture medium, or be incorporated during extraction and purification procedures. These impurities often consist of peptides with deletion or truncated sequences, incomplete deprotection, and byproducts generated during synthesis or the final cleavage process.
