Figure 2From: Spatio-temporal expression of MMP-2, MMP-9 and tissue kallikrein in uteroplacental units of the pregnant guinea-pig (Cavia porcellus)Western blot analysis of guinea-pig placental homogenates for MMP-2. A, Representative blot at days 20, 40 and 60 of pregnancy. Purified human proMMP-2 (hProMMP-2) yielded two bands with approximate molecular weights of 72 and 62 kDa. B, Mean ratio of active/total MMP-2 in three placental homogenates for each period showed no significant differences. DSCF posthoc comparisons after Kruskal-Wallis test.Back to article page
