Fig. 1From: Gelatinolytic activity in gingival crevicular fluid and saliva of growing patients with Marfan syndrome: a case-control studyGelatinolytic activity in GCF samples from Marfan patients and controls. Aliquots of a GFC sample were run on 12% polyacrilamide gel containing 1 mg/ml gelatin for gelatin zymography. Gels were incubated for 22 h at 37 °C to develop gelatinase activityBack to article page
