英文摘要in this work, a novel integrated sample preparation device for sds-assisted proteome analysis was developed, by which proteins dissolved in 4% (w/v) sds were first diluted by 50% methanol, and then sds was online removed by a hollow fiber membrane interface (hfmi) with 50 mm ammonium bicarbonate (ph 8.0) as an exchange buffer, finally digested by an immobilized enzyme reactor (imer). to evaluate the performance of such an integrated device, bovine serum albumin dissolved in 4% (w/v) sds as a model sample was analyzed; it could be found that similar to that obtained by direct analysis of bsa digests without sds (the sequence coverage of 60.3 +/- 1.0%, n=3), with hfmi as an interface for sds removal, bsa was identified with the sequence coverage of 61.0 +/- 1.0% (n=3). however, without sds removal by hfmi, bsa could not be digested by the imer and none peptides could be detected. in addition, such an integrated sample preparation device was also applied for the analysis of sds extracted proteins from rat brain, compared to those obtained by filter-aided sample preparation (fasp), not only the identified protein group and unique peptide number were increased by 12% and 39% respectively, but also the sample pretreatment time was shortened from 24 h to 4 h. all these results demonstrated that such an integrated sample preparation device would provide an alternative tool for sds assisted proteome analysis.
