description
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intergenic deletion
 
Mutation detailsA ~2.3 kb genomic fragment encompassing the four J-H segments and a flanking D-Q52 segment was replaced with a neomycin selection cassette. Homozygous mice do not produce rearranged immunoglobulin heavy chains. (J:52448)
