Agarose-GLAGLLAR-Azide (CCT-1581)


Agarose-GLAGLLAR-Azide is an agarose resin that is pre-activated with azide groups linked to the agarose resin through a short synthetic peptide containing a tryptic cleavage site. The alkyne-modified proteins, or their post-translationally modified forms, are captured from complex protein extracts on the Agarose-GLAGLLAR-Azide resin. Once covalently attached to the resin via copper catalyzed click chemistry, beads can be washed with highest stringency virtually eliminating any non-specifically bound proteins to yield a highly enriched population of nascent molecules. Upon tryptic digestion, this yields a highly pure peptide pool that is ideal for mass spectrometry (e.g., LC MS/MS) based analysis. Importantly, alkyne-modified targeted peptides can be easily identified by MS analysis, providing a confirmation by a mass shift of 172.10 Da
