description | Cre-mediated recombination in germinal center (GC) B cells as measured by EGFP expression from the Cd79b locus was determined in compound Igh-4tm1Cgn/Cd79btm1Cgn mice after immunization with NP-CG or SRBC. >85% of GC-B cells and IgG1+ memory B cells show cre-mediated recombination. |
molecularNote | Exons 5 and 6 coding for the Cd79b cytoplasmic domain were flanked by loxP sites and followed by a duplicated exon 5 carrying a premature stop codon. An frt-flanked IRES-EGFP cassette was cloned downstream of the duplicated exon 5. The neo cassette was removed by cre-mediated recombination. Crossing these mice with the appropriate cre mouse results in deletion of the original exons 5 and 6. The EGFP reporter expression will occur from the recombined allele. |
