Calcr^tm1Dgen

将细菌的lacZ基因插入，使得内源性基因驱动β-半乳糖苷酶的表达。在 whole brain, Harderian glands, heart 和淋巴结中可检测到微量的RNA转录本。lacZ表达出现在：大脑和垂体。 (Source: The lacZ gene was inserted into a bacterial system, with the native promoter driving beta-galactosidase expression, and faint RNA transcripts were observed in these tissues: brain, salivary glands, heart, and lymph nodes. Expression was detected in the brain and pituitary gland.)
