Mutation description

• Allele Type: Targeted
• Mutation: Insertion
• Mutation details: R130 and R137 codons were targeted to generate codons encoding alanine residues. A floxed neomycin resistance gene was inserted between exons 4 and 5. Crossing with mice expressing Cre in the germ line excised the floxed neo. Immunoblot and flow cytometry confirmed protein was expressed in spleen cell lysates from mutant mice. (J:92736)
