Myeloma, hybridoma, and thymoma cell lines have been successfully transfected for the Escherichia coli xanthine-guanine phosphoribosyltransferase gene (gpt) by using the plasmid vector pSV2-gpt. The transformed cells synthesize the bacterial enzyme 5-phospho-alpha-D-ribose-1-diphosphate:xanthine phosphoribosyltransferase (XGPRT; EC and have been maintained in selective medium for over 4 months. Lymphoid cell lines expressing a K immunoglobulin light chain were obtained by transfecting… CONTINUE READING
