The XylX6 assay reagent for the measurement of endo-xylanase (endo-1,4-β-xylanase) contains two components; 1) 4,6-O-(3-Ketobutylidene)-4-nitrophenyl-β-D-45-glucosyl-xylopentaoside and 2) β-xylosidase. The ketone blocking group prevents any hydrolytic action by the β-xylosidase or other exo-acting glycosidases on the XylX6 substrate. Incubation with an endo-xylanase generates a non-blocked colourimetric oligosaccharide that is rapidly hydrolysed by the ancillary β-xylosidase. The rate of formation of 4-nitrophenol is therefore directly related to the hydrolysis of XylX6 by the endo-xylanase. The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH = 10.0).

Note that standard curves relating the absorbance obtained using the XylX6 assay to endo-xylanase activity on the native substrates, wheat arabinoxylan and beechwood xylan, are provided in the Supporting Information file under the Documents tab.
