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.

Propargyl-PEG6-amine is a crosslinker with a hydrophilic PEG spacer which can increase the hydrophilicity of the molecule in aqueous environment. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
