Cellafluor is a fluorimetric reagent that can be used for the assay of cellulase (endo-1,4-β-glucanase). The reagent consists of 2 components:

1)      4,6-O-Benzylidene-4-methylumbelliferyl-β-cellotrioside

2)      β-glucosidase (Thermotoga maritima)

Upon incubation with a cellulase (endo-1,4-β-glucanase) enzyme, the functionalised trisaccharide is cleaved and the ancillary β-glucosidase can act to hydrolyse the fragment containing the 4-methylumbelliferyl group. The rate of formation of 4-methylumbelliferyl is directly proportional to the cellulase (endo-1,4-β-glucanase) activity. The assay reaction is terminated and full fluorescence obtained from the fluorophore by the addition of Tris buffer.

Quantitative fluorometric assay for the measurement of endo-1,4-β-glucanase.

Mangan, D., McCleary, B. V., Liadova, A., Ivory, R. & McCormack, N. (2014). Carbohydrate Research, 395, 47-51.

There is a growing demand for research tools to aid the scientific community in the search for improved cellulase enzymes for the biofuel industry. In this work, we describe a novel fluorometric assay for cellulase (endo-1,4-β-glucanase) which is based on the use of 4,6-O-benzylidene-4-methylumbelliferyl-β-cellotrioside (BzMUG3) in the presence of an ancillary β-glucosidase. This assay can be used quantitatively over a reasonable linear range, or qualitatively as a solution screening tool which may find extensive use in the area of metagenomics.

Novel substrates for the measurement of endo-1,4-β-glucanase (endo-cellulase).

McCleary, B. V., Mangan, D., Daly, R., Fort, S., Ivory, R. & McCormack, N. (2014). Carbohydrate Research, 385, 9-17.

A specific and sensitive substrate for the assay of endo-1,4-β-glucanase (cellulase) has been prepared. The substrate mixture comprises benzylidene end-blocked 2-chloro-4-nitrophenyl-β-cellotrioside (BzCNPG3) in the presence of thermostable β-glucosidase. Hydrolysis by exo-acting enzymes such as β-glucosidase and exo-β-glucanase is prevented by the presence of the benzylidene group on the non-reducing end D-glucosyl residue. On hydrolysis by cellulase, the 2-chloro-4-nitrophenyl-β-glycoside is immediately hydrolysed to 2-chloro-4-nitrophenol and free D-glucose by the β-glucosidase in the substrate mixture. The reaction is terminated and colour developed by the addition of a weak alkaline solution. The assay procedure is simple to use, specific, accurate, robust and readily adapted to automation. This procedure should find widespread applications in biomass enzymology and in the specific assay of endo-1,4-β-glucanase in general.
