Fig. 2From: SNPs of ACE1 (rs4343) and ACE2 (rs2285666) genes are linked to SARS-CoV-2 infection but not with the severity of diseaseAgarose gel electrophoresis of the PCR–RFLP products digested with BstUI restriction enzyme. The GG genotype was recognized as a single band at 122 bp, the AA genotype as two-bands at 100 and 22 bp and the AG genotype as three-bands at 122, 100 and 22 bpBack to article page
