Figure 1. Generation of the Cisd1 knockout (KO) mouse model. (A) The process of generating the CIsd1 knockout mouse. (B) Southern blot analysis. Genomic DNA was digested by Nde I and probed with a 5’ flanking probe. (C) The genotyping results are able to identify wild-type, heterozygous and homozygous knockout mice. The primers for PCR genotyping are F1: 5’-GTGTGAGTGTGTCTGTACCTAG-3’, F2: 5’-CTGTCTACATCAGAGCAGAACAC-3’ and R: 5’-CAACTGCACCACAAATCATGTGAG-3’. (D) Protein expression of Cisd1 and CIsd2 in wild-type (WT), Cisd1 KO and Cisd2 KO mice. Abbreviations: B: brain; H: heart; K: kidney. Mouse age, 4–5 weeks old.
