The MBG4 reagent contains a single substrate, namely 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-(3¹-β-D-cellotriosyl-glucoside) (BCNPBG4). The benzylidene acetal group prevents any hydrolytic action by exo-acting hydrolytic enzymes such as β-glucosidase or cellobiohydrolase.

Mixed linkage β-glucanase (endo-1,3:1,4-β-glucanase) / lichenase (EC 3.2.1.73) acts specifically to release 2-chloro-4-nitrophenol (CNP) from this substrate. The rate of release of CNP is directly related to the β-glucanase/lichenase activity in a sample. The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH = 10.0).

Note that the substrate is not hydrolysed by β-glucosidase or cellobiohydrolase. The substrate can be hydrolysed by certain endo-cellulases (e.g. Trichoderma sp.) but this does not result in an increase in absorbance.
