Mutation detailsHomologous recombination and subsequent in vitro cre mediated excision resulted in the replacement of endogenous sequence encompassing a 3' Igh-D element (DQ52) and the Igh-J elements with a recombined antibody variable region derived from a 4-hydroxy-3-nitrophenyl acetyl binding antibody (B1-8). The B1-8 variable region was modified to contain a point mutation in codon 92, inactivating the heptameric recombination signal sequence. Flow cytometry verified cell surface expression of the mutant protein product. (J:79556)
