Gene Affected Angptl8
Origin This Angptl8 KO strain has been established by CRISPR/Cas9 system at Kyoto University in 2014. Background strain: F344/Stm, gRNA target sequence: CCACAGCCCGATCGCTGAGGGAA, CCACGTGCAGCGACAGCAGCGTG, and PAM sequence: CCA. Mutaion: 7-bp deletion in the exon2 of Angptl8 gene. No Off Target effects are observed.
Strain characteristics Blood TG concentration (fasting and casual) falls to one-thirds to one-half. 2 lines are deposited, but there are no obvious differences in phenotypes between both lines (June, 2017).
Breeding Conditions Mating between heterozygous rats. KO rats have fertility.
Genotyping Check the product size by PCR. Primers are F : CATCTGTTGAGCAGGCAGAA R : GTTGAGTGGTGGCTTCCTTC. PCR condition is 94℃ 3 min, (94℃ 30 sec, 60℃ 1 min, 72℃ 2 min)x 45 cycles and 72℃ 3 min. Product sizes are 232 bp (WT) and 225 bp (KO).
