A) 4-20% SDS-page gradient gel of sFlt and mvsFlt (650 kDa LCR) following 12 hour treatment with MMP-7 at high, medium and low molar ratios of MMP-7 to sFlt, which correspond to 1:1, 1:2 and 1:4 molar ratios of MMP-7 to sFlt. Band intensity was normalized to the no MMP-7 treatment within each group and background was subtracted from each sample using the blank well. B) Quantification of 4-20% gradient gel of sFlt and mvsFlt treated with MMP-7 at high, medium, and low molar ratios of sFlt to MMP-7 for 12 hours (*p<0.05; **p<0.01).
