What is Peptide Purity?

we provide peptides that exceed 99% purity. Using state-of-the-art solution and solid phase peptide synthetic technology, Peptide Sciences is able to offer the finest quality peptides and proteins fit for any research study or application. Peptide purity is achieved and verified through uncompromising manufacturing and production processes, quality control measures, and the implementation of both high-performance liquid chromatography and mass spectrometry analysis.

Generally, the higher the peptide purity level, the more favorable the preparation; critically, for certain applications (such as in vitro studies or clinical trials), only exceedingly pure peptides will be appropriate (greater than 98% purity). However, there are some applications for which a lower peptide purity would be acceptable. The minimum recommended peptide purity level for a given application will therefore depend upon that specific application. Examples of minimum acceptable purity levels are as follows.
