Gene Affected Tac1 (tachykinin, precursor 1) , IL2RA/ヒトHA-tag/ヒトインフルエンザウイルスT2A/Thosea asignaウイルス
Origin Background strain: Long-Evans (Iar:Long-Evans, Institute for Animal Reproduction). Details of the introduced gene: This rat strain was generated by inserting the "IL2RA/HA-T2A" sequence into the start codon (methionine) within the second exon of the Tachykinin precursor 1 (Tac1) gene in fertilized rat eggs using the CRISPR/Cas9 system (Combi-CRISPR). A single-base deletion is observed in the first intron of the Tac1 gene due to NHEJ after a double-strand break induced by Combi-CRISPR. Target site sequence: Wild-type: GTTTGGAGAAATGTTCGACC(TGG) Knock-in strain: GTTTGGAGAAATGTTCーACC(TGG)       (  ) indicates the PAM sequence.
Strain characteristics IL2RA/HA is expressed under the control of the Tac1 promoter.
Breeding Conditions Good breeding performance. Maintained by mating heterozygous rats with Long-Evans rats.
Genotyping Forward primer: 5'-CGTCAGTAGCCTTCTTAAAGGGT (within the first intron) Reverse primer: 5'-GTTCTGGGCAATAAGCCTTGTG (within the second intron) Amplified fragment size: Wild-type: 463 bp; Knock-in: 1399 bp In heterozygotes, both wild-type and knock-in amplifications are detected simultaneously.
