Active gelatinases digest gelatin embedded in a polyacrylamide gel. After Coomassie staining, areas of degradation are visible as clear bands against a darkly stained …
WebMar 16, 2024 · Collagen zymography is an SDS-PAGE–based method for detecting both the proenzyme and active forms of collagenases. Although collagen zymography is used for assessment of the matrix metalloproteinases MMP-1 and MMP-13, it can be difficult to detect these collagenases due to technical issues. WebGelatin zymography, first described by Heussen and Dowdle in the 1980s, is a widely used valuable tool in research and diagnostics. The technique identifies gelatinases by the degradation of their preferential substrate as well as by their molecular weight (kDa).
