Sensitive and rapid electrochemical bioassay of glycosidase activity

Analyst. 2006 Aug;131(8):889-91. doi: 10.1039/b605943k. Epub 2006 Jul 6.

Abstract

Here we present a highly sensitive, rapid and simple electrochemical assay for glycosidases based on treatment of the glycosidase with the appropriate p-nitrophenyl glycoside and anodic detection of released p-nitrophenol. The attractive characteristics of the new bioassay should facilitate advanced glycomic research and routine clinical diagnostics since glycosidases are associated with various diseases.
