Gene Affected interleukin 2 receptor gamma (Il2rg)
Origin 【This strain is provided by the University of Tokyo (cooperative facility)】 This strain was established by CRISPR/Cas9 targeting rat Il2rg gene using electroporation. background strain: F344/Jcl. gRNA: CCAACCTCACTATGCACTATAGG (PAM sequence: CCA). Cas9: mRNA transcripted from T7-NLS hCas9-pA (RDB13130). Off target analysis has not yet been conducted.
Strain characteristics This strain shows severe combined immunodeficiency (SCID) caused by 5-bp deletion of Il2rg gene. This strain grows normally under SPF condition.
Breeding Conditions mating between hemizygous male and homozygous female rats
Genotyping PCR: primers (TTGCTGACTTCTATGGACCTTAAA and TTCATCTGGTCTGAACTGATAACTTAT). product size: wild 292 bp and mutant 287 bp
