Gene: H2-Ab1  Location: Chr17:34263227-34269418 bp, + strand  Genetic Position: Chr17, 17.98 cM
Germline Transmission:  Earliest citation of germline transmission: J:74418
Parent Cell Line:  D3 (ES Cell)
Strain of Origin:  129S2/SvPas
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsA neomycin selection cassette was inserted into exon 2. In addition, the ES cell line used was derived from the 129S2/SvPas strain, which carries a deletion in the promoter region of H2-Ea. Consequently, these MHC class II molecule-deficient mice lacked cell surface expression of both class II-A and class II-E MHC proteins. (J:74418)
