Mutation detailsES cells containing Tcrbtm1Slek, which contain a loxP site in place of the Dbeta2-Jbeta2 gene cluster, were additionally targeted to generate a TCRb allele with only a single Dbeta and Jbeta gene segment. Five of the six Jbeta1 segments (Jbeta1.2-1.6) were replaced with a loxP-flanked neomycin cassette. The neomycin resistance gene was then removed by cre-mediated recombination. This allele thus has a 2 kb deletion of the Dbeta2-Jbeta2 gene segment cluster, and a 1.5 kb deletion of five Jbeta1 gene segments. As a result, all TCRbeta chain genes assembled on this allele use the Dbeta1 and Jbeta1.1 gene segments. (J:143738)
