• Alliance: Cd79a^tm2Pld page

Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:87492
• Parent Cell Line: BALB/c-I (ES Cell)
• Strain of Origin: BALB/cJ

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: Exons 2 and 3 were replaced by a loxP site, an EGFP gene, a cDNA cassette containing exons 2 - 5 in inverse orientation and a floxed neomycin resistance gene. Lack of mRNA expression was demonstrated by Northern blot analysis. Although designed to be a cre dependent conditional allele capable of expressing either EGFP or Ig-alpha, neither of the inserted genes were ever expressed. (J:87492)
