How to avoid keratin contamination in protein samples for mass spectrometry analysis?
Keratin mainly originates from skin flakes and dandruff. During the processes of dyeing, bleaching, gel cutting, and enzymatic hydrolysis, keratin can easily be introduced into protein samples. Therefore, it's important to wear clean gloves, masks, and lab coats during experiments and to thoroughly clean the laboratory equipment.
