Peptide purification with flash column chromatography – a beginner’s experience

With this post I would like to introduce a new colleague, Beth Denton, who I recently convinced to try flash chromatography for purification of peptides. She has kindly agreed to share her new flash column chromatography experience here.  So, now, here’s Beth.

As a peptide chemist, I was trained to purify my peptides with reversed-phase HPLC, just as many a peptide chemist before me. Despite the hundreds of hours I’ve logged in front of an HPLC, injecting samples and collecting peak fractions, I can’t imagine using any other method to purify my freshly synthesized and cleaved peptides.  In fact, you’d be hard pressed to convince me to try something else.  But here I am, trying something new.  Wish me luck!

In this post, I’ll describe my experiences using flash chromatography to purify a new peptide sample.
