Peptide purity refers to the proportion of the desired peptide relative to other contaminants and impurities in a sample. Peptide purity plays a critical role in the success and integrity of your research projects. Here is a list of recommended purity level for some common peptide applications for your reference. Certain applications (e.g. clinical trials) will require GMP grade peptides and FDA approval. Creative Peptides provides research grade peptides which are for research use only. Not to be used for clinical, diagnostic or therapeutic purposes, or human consumption.
