Figure 2. (A-C). RT-PCR gel images showing the detection of Kiss1 gene in the blood (A), the testis (B) in male Wistar rats and their relative expression (C). Fig. 2A - samples 2, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13 positive bands for the expressed Kiss1 genes at 100bp. 4 represents group A, 2 represents group B, 1 and 3 represents group C. Fig. 2B - samples A, B and C are positive bands for the expressed Kiss1 genes at 100bp. A represents group A, B represents group B and C represents group C. L is a 100bp-1000bp DNA ladder (molecular marker).
