这个基因陷阱载体插入在第7和8外显子之间。通过在杂合子小鼠胚胎成纤维细胞中进行 Western Blot 分析，确实证实了蛋白质表达量的降低。原位杂交确认了lacZ融合转录本的广泛表达。 (Gene trap vector inserted between exons 7 and 8. Reduced protein expression confirmed by Western blot on heterozygous mouse embryonic fibroblasts. In situ hybridization confirmed ubiquitous expression of the lacZ fusion transcript, source: original text)
