Recommended Peptide Purity

Hanhong Chemical proposes a range of different purity levels to help you make the right choice for your application. We proposes four levels of purity for our custom peptide synthesis services. Peptides with purity greater than 70% are always used for generating or testing antibodis. Peptides with purity level greater than 85% are usually used in enzymology or biological activity studies. Peptides with purity greater than 95% are excellent for quantitative analysis. We also provide high purity peptides with purity greater than 98% in large quantities with commercial applications for our industrial customers. The quality of the peptides is verified by both HPLC and Mass Spectrometry of which the QC data is included in the peptide delivery.
