ABSTRACT
Cell adhesive molecular P-selectin was cloned, expressed and anchored on CHO cell membrane through GPI for selection specific antibodies. Total human platelet RNA was extracted and the functional segment of P-selectin gene was cloned by RT-PCR. The P-selectin functional segment gene was cloned into a eukaryotic expression vector pMCEw2-GPI containing an attenuated neo gene together with a downstream GPI, which was synthesized by overlapping PCR. The recombinant plasmid pMCEw2-GPI-P-selectin was then transfected to CHO(dhfr-) cells and screened with G418. ELISA, western-blot and immunofluorescence were carried out to detect the stability of P-selection expression on cell membrane. These results provided a necessary basis for the following study of selection the antibodies targeting P-selectin.
