Exon 2被通过同源重组替换为一个PGK-neo cassette。RT-PCR和 Western blot结果显示滋养层干细胞中存在一段剪切的RNA和蛋白质产物,但硫酸软骨素的合成并未受到影响。(来源:J:103125)

Exon 2 was replaced by a PGK-neo cassette via homologous recombination. RT-PCR and western blot analysis detected a truncated RNA and protein product in trophoblast stem cells, however heparan sulfate synthesis does not occur. (J:103125)
