description
Allele Type:    Targeted (Modified regulatory region, Null/knockout)
Mutations:    Insertion, Intergenic deletion
 
Mutation detailsThe TEA (T early alpha) promoter was replaced with a loxP site flanked neomycin resistance gene cassette. The neo cassette was removed through subsequent cre-mediated recombination. No gross deficiency was found in alphabeta TCR expression or alphabeta T cell development in mutant mice. (J:97736)
