Zymographic assay of gelatinase activity in pre-surgery plasma samples. (M = malignant mammary neoplasia, B = benign mammary neoplasia, C = control, N = normal dog). Bands corresponding to pro-MMP-2, pro-MMP-9 and active form of MMP-9 were observed in dogs with adenomas and carcinomas (B, M). Bands corresponding to pro-MMP-9 and pro-MMP-2 were observed in the control dog, and A2058 melanoma cells (C) were used as the control for active MMP-9.
