Mutation detailsA promoterless lacZ gene followed by a neomycin selection cassette was fused in frame directly following the translation start codon. Northern blot analysis on RNA derived from E13.5 homozygous embryos demonstrated that no wild-type transcript was detectable. Flow cytometry analysis on cells derived from thymus, spleen and lymph nodes of homozygous mice confirmed that no stable encoded protein was expressed on the cell surface. (J:68069)
