Common Name
B-Rag2 KO rats
Source/Investigator
Bcgen (Beijing Biocytogen Co., Ltd)
Related Genes
Rag2 (recombination activating gene 2)
Species
Sprague Dawley
Appearance
White
Genotypes
Rag2KO (mut/mut)
Development
The Rag2KO rat was developed using targeted TALEN technology in the Sprague-Dawley strain, and this model possesses a 121 bp deletion within Exon 3 on chromosome 3. This strain was maintained by mating homozygous males with homozygous females on a Sprague-Dawley genetic background.
Description
The recombinant-activating gene 2 (Rag2) plays an important role in the rearrangement and recombination of the genes of immunoglobulin and T cell receptor molecules during the initiation of V(D)J recombination. Loss of Rag2 protein leads to no mature T and B cells, the critical components of the adaptive immune system.
