RESULTS A eukaryotic expression system for high expression humanmutantCD59 were successfully set up : The recombinant PALTER-MAX plasmid containing human mutantCD59 cDNA and PCDNA plasmid were co-transfected into CHO cell by cation lipoid mediating method ;and the cells were grown in F12 medium containing 400ug/ml G418 for 14 days, positive clones were grown in RPMI1640 medium to get stable expressing cell lines . Highly expressing clones were selected by flow cytometry ,and were named PALTER-CD59-CHO1PALTER-CD59-CHO2 . Flow cytometry indicated that expression rates of PALTER-CD59-CHO1 and PALTER-CD59-CHO2 were 53.7%and 54.5%. Further more, Stable highly expressing CHO cell lines were more detected by immunocytochemistry and immunofluorescence technology . PALTER-CD59 -CHO1 and PALTER-CD59-CHO2 were grown in RPMI1640 to get a large of cells . CD59 protein were obtained by spalling PALTER- CD59- CHO1 and PALTER - CD59 - CHO2 cells . Stable highly expressing cells were further validated by SDS-PAGE, immunoblot analysis and solid enzyme immunoassay . PALTER - CD59 - CHO1 and PALTER - CD59 - CHO2 were glycated in RPMI1640 of 50mM ribose for 72 hours .BCECF releasing test indicted that the releasing rate of PALTER-CD59-CHO1 or PALTER-CD59-CHO2 was less high than PALTER-CHO ,and the releasing rate of glycated PALTER-CD59 -CHOI or PALTER-CD59-CHO2 was higher than unglycated ones .
