The Purification Insights Blog

A critical and fundamental factor in both analytical and preparative chromatography is the use of true buffers. In other words, mobile phases with buffering capacity. For example, in peptide purification, there are concentrated bands of various..

Peptide therapeutic agents are enjoying increasing success but they are challenging to produce and, not least, to purify. Purity requirements are, in fact, approaching those for small molecules. Synthesis generates a crude mixture containing..

The global diabetes pandemic has created a massive demand for insulin, especially in China, which is expected to soon have half the world’s diabetes patients. Meeting this demand means developing extremely efficient production methods that can..

The purity requirements for therapeutic peptides are very stringent, but synthesis generates a crude peptide mixture containing failed sequences and chemical variants, while recombinant peptides have a considerable bioburden from the host cell...
