Fig. 2From: Follicular fluid biomarkers for prediction of human IVF outcome in women with poor ovarian responseRepresentative MMP gels per clinical group. MMP-2 and MMP-9 activity in follicular liquids. Representative gelatin zymography of the three study groups: A EA, B EB, and C EC, showing two forms of MMP-9, a 92 kDa proenzyme and a 84 kDa enzyme activity. MMP-2 evidenced the 72 kDa pro-enzyme form. Supernatant of U937 cells was used as a marker of gelatinolytic activityBack to article page
