Figure 1From: Serum antibody response to Human papillomavirus (HPV) infections detected by a novel ELISA technique based on denatured recombinant HPV16 L1, L2, E4, E6 and E7 proteinsAnalysis of purified proteins by SDS-PAGE. The purified HPV16 proteins E4, E6, E7, L1 and L2 were run on a polyacrilamide gel electrophoresis and stained by Coomassie blue. Each protein is indicated on the top of the corresponding lane. The weight of the molecular mass markers (lane M) is indicated on the left of the figure.Back to article page
