Fig. 1From: 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 of ACE2 G8790A digested with AluI restriction enzyme. The GG genotype was recognized as a single band at 817 bp, the AA genotype as two bands at 589 and 228 bp and the GA genotype as three bands at 817, 589 and 228 bpBack to article page
