Gene Affected recombination activating 2(Rag2)
Origin 【This strain is provided by the University of Tokyo (cooperative facility)】This strain was established by targeting Rag2 gene in F344/Jcl using CRISPR/Cas9 system. gRNA to Rag2: AACATAGCCTTAATTCAACCAGG (PAM: last AGG); Cas 9 mRNA transcribed from T7-NLS hCas9-pA (RDB13130) was used for the system. Gene transfer was performed by electroporation. The off-target sites have not been identified yet.
Strain characteristics This strain shows severe combined immunodeficiency (SCID) caused by 1-bp insertion in Rag2 gene on chromosome 3. This strain grows normally under SPF condition.
Breeding Conditions Mating male homozygous and female homozygous.
Genotyping Transgenic rats can be distinguished by PCR, electrophoresis and Sanger sequencing. Rag2: Wilde type: 381bp, Mutant: 382bp, Primer:GGGGAGAAGGTGTCTTACGG, AGGTGGGAGGTAGCAGGAAT
