| 英文摘要 | Precisely quantifying the membrane protein expression level on cell surfaces is of vital importance for early cancer diagnosis and efficient treatment. we demonstrate that gold nanoparticle bioconjugated by a rationally designed peptide as nanoprobe possesses selective labeling and accurate quantification capacity of integrin gpilb/iiia on the human erythroleukemia cell line. through selective recognition and marking of integrin, two-photon photoluminescence of the nanoprobe is exploited for direct observation of protein spatial distribution on cell membrane. more importantly, utilizing intrinsic enzyme-like catalysis property of the nanoprobe, the expression level of integrin on human erythroleukemia cells can be quantitatively counted in an amplified and reliable colorimetric assay without cell lysis and protein extraction process. in addition, the analysis of the correlation between the gold nanoparticle and the membrane protein via relevant inductively coupled plasma mass spectrometry measurement verifies the reliability of the new analytical method. it is anticipated that this facile and efficient strategy holds a great promise for a rapid, precise, and reliable quantification of interested functional membrane proteins on the cell surface. |
