Effect of concentration of A. indica seed extract on expression of nonstructural gene NS3 (A) and NS5A (B). RT-PCR results: lane 1 in A positive control, lane 2-7: increasing extract concentrations (100, 200, 300, 400, 500, 600 µg/mL), lane 8: 1kb DNA ladder. B., lane 1: 1kb DNA ladder, lane 2: positive control, lane 3-8: increasing extract concentrations (100, 200, 300, 400, 500, 600 µg/mL).
