(A) Tri-ARMS PCR assay based genotyping of CXCL10 rs5606198 (G/A) polymorphism on 2.5% agarose gel. Lane L shows 1000 bp molecular marker, lane 1 and 2 shows positive control with GA genotype. Lanes 3, 4 and 5,6 represents GA genotype with band size of 545 and 295bp. (B) T-ARMS PCR assay based genotyping of CXCL9 rs2276886 (G/A) polymorphism on 2.5% agarose gel. Lane L shows 1000 bp molecular marker, lane 1 shows positive control. Lanes 3, 4 and 5 shows GG genotype of 232 bp along with control band of 595 bp. Lanes 1, 7 represent GA genotype with both bands of 4081 bp and 232 bp along with control of 595 bp. Lane 2 represents AA genotype with both bands of 408bp and 595bp.
