摘要： In order to further the study the properties of the mouse Fc gamma receptor III (moFc gamma RIII) and mouse gamma chain their genes were co-expressed in cultured COS7 cell and a stable cell line was produced. The moFc gamma RIII and gamma chain genes were isolated from the mouse peripheral blood leucocyte mRNA, amplified separately by RT-PCR, and eukaryotic expression plasmids of pc3mRIII and pc3m gamma were constructed. After identification by restriction digestion and PCR, the recombinant plasmids of the Pvu I-linearised pc3mRIII and the Pvu I-linearised pc3m gamma were co-transfected into COS7 cells with lipofectamine. Cloning by limiting dilution after selective culture with G418, established a stably-transfected cell line successfully. Co-expression of the moFc gamma RIII and gamma chain RNA was confirmed by RT-PCR, and functional expression was identified by flow cytometry and rosetting assay. The moFc gamma RIII expressed on the surface of selected cell line shows similar specificity. As that of native moFc gamma RIII and provides a novel experimental system to study further the function of moFc gamma RIII in a convenient replicating cell line.
