WebZymography is any technique that can be used to study the effects of hydrolases acting on any biological sample. Thus, depending on substrate, zymographic assays can use organic molecules including peptides, lipids, and nucleic acids, detecting, among others, proteases, lipases, and nucleases. This chapter will concentrate on zymographic assays ... 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). We here describe detailed methodolog …
Zymography is an electrophoretic technique for the detection of hydrolytic enzymes, based on the substrate repertoire of the enzyme. Three types of zymography are used; in gel zymography, in situ zymography and in vivo zymography For instance, gelatin embedded in a polyacrylamide gel will be digested by active gelatinases run through the gel.
