英文摘要 | due to their extremely hydrophobic nature, the analysis of integral membrane proteins (imps) is of great challenge. although various additives have been applied to improve the solubility of imps, they still suffer from low solubilization efficiency, incompatibility with trypsin digestion, or interference with ms detection. herein, the systematic study on the effect of ionic liquid structure on membrane protein solubilization and trypsin biocompatibility was performed, based on which 1-dodecyl-3-methylimidazolium chloride (c12im-cl) was selected for the sample preparation of imps. compared with other commonly used additives, such as sodium dodecyl sulfate (sds), rapigest, and methanol, c12im-cl showed the best performance. in addition, with a strong cation exchange trap column, it could be easily removed after trypsin digestion, which not only was beneficial to avoid protein precipitation during digestion but also had no adverse effect on lc-ms-based separation and detection. such a c12im-cl-assisted sample preparation method was further applied to the membrane proteome analysis of rat brain. compared with the sds-assisted method, 1.4 and 3.5 times improvement on the identified imp and hydrophobic peptide number were achieved (251 vs 178, and 982 vs 279). all these results demonstrated that the c12im-cl-assisted sample preparation method is of great promise to promote the large-scale membrane proteome profiling. |
