  • Assay method for hemicellulases using a colored substrate
    Patent number: 5496707
    Abstract: The present invention provides an assay method for hemicellulases comprising a) directly dyeing, using a reactive dye, an insoluble natural product, or a modified form of a natural fibre material; and b) adding the enzyme to the dyed product produced in step a) and, after a specific incubation period, separating the liquid component from the insoluble dyed product, e.g. by a simple filtration, and determining the amount of dyestuff liberated in the the separated solution by spectrophotometric means. A combined mixing and dispensing device for use in the method of the present invention is also provided.
