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。RT-PCR检测到在大脑、脊髓、眼睛、肾脏、垂体和子宫中存在基因转录。β-半乳糖苷酶的表达在大脑、眼睛、肾脏、膀胱和睾丸中可被检测到。 (Source: The inserted bacterial lacZ gene is expressed under the endogenous promoter, with detection of a transcript in brain, spinal cord, eye, kidney, pituitary, and uterus by RT-PCR. Beta-galactosidase activity is observed in brain, eyes, kidney, urinary bladder, and testis.)
