一种基因陷阱载体,它包含了一个插入在基因210bp上游于exon7之前的IRES-Beta-geo表达/筛选元件。通过对小鼠血清的 Western blot 分析,证实了这个等位基因未表达出可检测到的蛋白质。(来源:J:76090)

A gene trap vector that contained an IRES-Beta-geo expression/selection cassette inserted into the gene 210 bp upstream of exon 7. Western blot analysis of mouse serum confirmed that no detectable protein was expressed from this allele. (J:76090)
