Rag2/OT-II (11490)

Genetic Background:

C57BL/6 Background

Origin:

The OT-II microinjected model was developed by Dr. Francis Carbone of Monash Medical School and Dr. William R. Heath of the Walter and Eliza Hall Institute. The model was created by microinjecting the rearranged Valpha2 and Vbeta5 T cell receptor into B6 x B6.C-H2bm1 blastocysts. Taconic received stock from Keio University in June 2001, and the mice were rederived by backcrossing to C57BL/6NTac. OT-II transgenic mice were crossed with a homozygous C57BL/6NTac Rag2 targeted mutation model (RAGN12-M), and then intercrossed for homozygosity at the Rag2 allele. The model was rederived by embryo transfer and is maintained by mating of mice that are homozygous for Rag2 disruption and heterozygous for the OT-II transgene to mice that are homozygous for the Rag2 disruption and wild type for OT-II.
