Peptide Purity Explained: 99% vs 98%

Is 99% purity really necessary for research? The short answer is yes. Impurities can include synthesis byproducts, trifluoroacetic acid (TFA) salts, or truncated sequences.

We analyze HPLC chromatograms to show you what a "dirty" peak looks like and why high purity correlates with better research data.
