Method Primary source abstract: "[Investigators] evaluated electroporation as a method to introduce foreign genes into cynomolgus monkey ES cells. [Their] examination has allowed [them] to establish a protocol producing about 100 stably transfected clones from 10^(7) cynomolgus monkey ES cells."
Comments P.69 right column 2nd paragraph: "For preliminary research, [investigators] optimized electroporation conditions to introduce foreign genes into cynomolgus monkey ES cells [primary source]. Using an SV40-neo expression vector, about 100 stable clones can be consistently produced from 10^7 monkey ES cells after drug selection. Differences in efficiency, however, were observed for other ES cell lines. In addition, [they] compared the transcriptional activities of the PGK-1 [Phosphoglycerate kinase 1], CMV [Cytomegalovirus], and SV40 promoters in cynomolgus monkey ES cells. Although the PGK-1 and SV40 promoters work efficiently in monkey ES cells, the CMV promoter displayed significantly lower activity compared to the others."
