中文摘要high throughput tryptic digestion via poly (acrylamide-co-methylenebisacrylamide) monolith based immobilized enzyme reactor
英文摘要a poly (acrylamide-co-methylenebisacrylamide) (poly (aam-co-mba)) monolith was prepared by thermal polymerization in the 100 or 250 mu m i.d. capillary. the monolithic support was activated by ethylenediamine followed by glutaraldehyde. trypsin was then introduced to form an immobilized enzyme reactor (imer). the prepared imer showed a reliable mechanical stability and permeability (permeability constant k = 2.65 x 10(-13) m(2)). with bsa as the model protein, efficient digestion was completed within 20 s, yielding the sequence coverage of 57%, better than that obtained from the traditional in-solution digestion (42%), which took about 12 h. moreover. bsa down to femtomole was efficiently digested by the imer and positively identified by matrix assisted laser desorption/ionization-time of flight mass spectrometry (maldi-tof ms). to test the applicability of imer for complex sample profiling, proteins extracted from escherichia coli were digested by the imer and further analyzed by nanoreversed phase liquid chromatography-electrospray ionization-mass spectrometry (nanorplc-esi-ms/ms). in comparison to in-solution digestion, despite slightly fewer proteins were positively identified at a false discovery rate (fdr) of similar to 1% (333 vs 411), the digestion time used was largely shortened (20 s vs 24 h), implying superior digestion performance for the high throughput analysis of complex samples.
