将细菌的lacZ基因插入，使其由内源性基因驱动β-半乳糖苷酶的表达。RNA转录本在多种器官中检测到，而这个等位基因的β-半乳糖苷酶表达在大脑、脊髓、视网膜、心脏、肾脏、垂体、睾丸、前列腺和子宫中可被检测到。 (Source: The inserted bacterial lacZ gene is expressed under the endogenous promoter, with detectable beta-galactosidase activity in the brain, spinal cord, retina, heart, kidney, pituitary, testes, prostate, and cervix, based on RNA transcripts observed in various organs.)
