Figure 1: PCR product of the E. ocellatus serine proteases. Analysis of PCR amplification products by 0.7% agarose gel electrophoresis. Bands were visualised using the ultraviolet transillumination. Lane 2: represents the amplified PCR product (circled) of about 800 bp from E. ocellatus venom glands cDNA compared with Lane 1:1 kb ladder DNA-marker bands, of known molecular weight. Lanes 3 and 4 represent a H2O negative control and a SOD positive control, respectively.
