Ccr1l1^tm1Dgen

A bacterial lacZ gene was inserted into the gene such that the endogenous gene promoter drives expression of beta-galactosidase. While RT-PCR analysis detects a high level of gene transcript in lymph nodes, bone marrow, pituitary gland, small intestine, prostate gland, ovary and uterus, beta-galactosidase expression from this allele is not detectable.
