英文摘要single chain variable fragment (scfv) displaying the m13 phage library was covalently immobilized on magnetic microspheres and used as a protein equalizer for the treatment of human serum. first, scfv displaying m13 phage library functionalized magnetic microspheres (scfv@m13@mm) was incubated with a human serum sample. second, captured proteins on scfv@m13@mm were eluted with 2 m nacl, so mm glycine-hydrochloric acid (gly-hcl), and 20% (v/v) acetonitrile with 0.5% (v/v) trifluoroacetic acid in sequence. finally, the tightly bonded proteins were released by the treatment with thrombin. the eluates were first analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) with silver staining. results indicated that the difference of protein concentration was reduced obviously in nacl and gly-hcl fractions compared with untreated human serum sample. the eluates were also digested with trypsin, followed by online 2d-strong cation exchange (scx)-rplc-esi-ms/ms analysis. results demonstrated that the number of proteins identified from an scfv@m13@mm treated human serum sample was improved 100% compared with that from the untreated sample. in addition, the spectral count of 10 high abundance proteins (serum albumin, serotransferrin, alpha-2-macroglobulin, alpha-1-antitrypsin, apolipoprotein b-100, ig gamma-2 chain c region, haptoglobin, hemopodn, alpha-1-acid glycoprotein 1, and alpha-2-hs-glycoprotein) decreased evidently after scfv@m13@mm treatment. all these results demonstrate that scfv@m13@mm could efficiently remove high-abundance proteins, reduce the protein concentration difference of human serum, and result in more protein identification.
