Figure 2: Proteoglycans expression in human prostate tumours. (a) Representative gels are shown. (b) Intensity of the amplified DNA fragments normalised to that of GAPDH. The graphs show the mean expression levels from triplicate experiments (±SD), (OriginPro 8.1). 4, 5, 51, and 55 are representative prostate tumours. M: 1 Kb-Plus DNA marker (Medigen).
