Abstract
Electrostatic repulsion-hydrophilic interaction chromatography (ERLIC) has been introduced recently for phosphopeptide enrichment. Here we compared ERLIC with the well-established SCX-IMAC for identifying phosphopeptides in EGF-treated A431 cells. The ERLIC approach detected a higher number of phosphopeptides (17 311) than SCX-IMAC (4850), but it only detected 926 unique phosphopeptides compared to 1315 in SCX-IMAC. Only 12% unique phosphopeptides were common to both approaches, suggesting that more comprehensive phosphoproteomes could be generated by complementing SCX-IMAC with ERLIC.Entities:
