Increasing your peptide purity using a focused gradient with flash chromatography

Reversed phase flash chromatography is increasingly being utilized by peptide chemists to decrease purification time and efforts. The larger particles used in flash columns enable large crude sample loads and can lead to highly pure peptide samples despite lower resolution when compared to traditional HPLC methods. However, there are some situations where the purity achieved isn’t sufficient. Then what can you do?

In today’s post, I’ll describe using a focused gradient to achieve higher purity peptides than is possible with a more traditional linear gradient.
