Representative blot of placental homogenates from days 20, 40 and 60 of pregnancy for FLT-1 and eNOS. Purified human Flt-1 and eNOS yielded bands with approximate molecular weights of 180 and 140 kDa respectively. No significant differences were observed between the means of the 3 homogenates included in each study period, using one-way analysis of variance and Tukey's Multiple Comparison post-hoc test.
