VI 16832 is a broad spectrum Type I kinase inhibitor which can be used as an enrichment tool for the comparative expression analysis of protein kinases in different cancer cell lines.
VI 16832 is a broad spectrum Type I kinase inhibitor[1]. Phosphoproteomics analysis of VI 16832-enriched fractions from MV4-11, HCT116, or 435S cells results in more than 8500 phosphopeptide identifications. These translate into almost 1700 distinct phosphopeptide species derived from 212 different members of the protein kinase superfamily. Analysis of VI 16832-retained proteins from the three cancer cell lines considerably increases the overall number of identified phosphorylation sites on protein kinases. Considering the sum of all phosphopeptide intensities as a measure for VI 16832-enriched protein amount, more than 80% is derived from protein kinases[2].
