Click-&-Go Protein Enrichment Kit *for capture of alkyne-tagged proteins*

Click-&-Go™ Protein Enrichment Kit is an efficient, biotin-streptavidin free tool for capture of alkyne-modified proteins on an azide-agarose resin. The alkyne modification can occur via metabolic feeding, enzymatic addition, or chemical modification. Alkyne-modified proteins, or their post-translationally modified forms, are captured from complex protein extracts on the azide-agarose resin supplied. Once covalently attached to the resin via copper catalysed 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 protease digestion, this yields a highly pure peptide pool that is ideal for mass spectrometry (e.g., LC MS/MS) based analysis.

The biotin-free enrichment improves signal to noise by eliminating non-specific binding and increasing selectivity, thus improving detection of low abundant proteins. This approach is fully compatible with widely used MS techniques including iTRAQ and ICAT.

The biotin-free, covalent capture approach is superior to biotin or lectin based enrichment approaches, and ideal for proteomics, biomarker discovery, post-translational modification (PTM) analysis, and more.
