ProteoSpin™ On-Column Proteolytic Digestion Kit

This kit is highly efficient in the enzymatic digestion of simple and complex protein samples using trypsin and the subsequent purification of the resulting peptides using a convenient spin column format. Trypsin is added to the protein sample and bound to the column. Salts are washed away and the trypsin is then activated to digest proteins. Peptides are then eluted in a small volume and ready for downstream analysis. The peptides generated are complete, with no additional artifacts being detected in mass spectrometry. Fifteen micrograms of protein can be processed, digested and purified with each spin column with about 20 minutes of hands-on time (plus trypsin incubation). The simultaneous protein digestion and volumetric concentration of the purified peptides makes the kit a convenient method for preparing peptides to be analyzed by many downstream applications such as mass spectrometry and more.
