The cup-plate technique makes it possible to detect enzyme activities after diffusion into buffered, substrate-containing agar gels. This technique has been used after nondenaturing blotting transfer in order to detect depolymerizing enzyme activities once analytical protein separation (e.g., by electrophoresis, electrofocusing, or titration curves) has been completed. This rapid and very sensitive method was successfully applied to the enzymes polygalacturonate lyase, polygalacturonate hydrolase, endoglucanase, and xylan hydrolase. Other possible applications are presented.
