Generation of 14E06 KI mice. (A) Generation of the VDJH 14E06 KI mouse. Top: Targeting construct for the rearranged VDJH 14E06 and a FRT-flanked pkg-neo selection cassette. Middle: Mouse H chain locus with indication of the replaced D and J1-4 gene segments. Dashed lines indicate terminal points of homologous recombination. Bottom: Integrated transgene after flp mediated excision of the FRT-flanked neomycin selection gene. (B) Generation of the VJκ 14E06 KI mouse. Top: Targeting construct for the rearranged VJκ 14E06. Middle: Mouse κ L chain locus with indication of the replaced J1-5 gene segments. Bottom: integrated transgene after flp mediated excision of the FRT-flanked neomycin selection gene. (C) Detection of transgenic anti-TG2 BCR. Spleen cells from WT C57Bl/6 mice (obtained from Janvier Laboratoires), 14E06 L chain single KI and H chain single KI littermate control mice, and H and L chain double KI mice on C57Bl/6 background were stained using anti-B220 and an antibody specific for the H and L chain combination of 14E06 (anti-14E06) or mTG2 tetramers. Data are representative of two independent experiments.
