UV-method for the determination of D-Glucuronic Acid or
D-Galacturonic Acid in hydrolysates of plant material and
polysaccharides and other materials

                                       (Uronate dehydrogenase; UDH)
(1) D-Glucuronic acid + NAD+ + H2O → D-glucarate + NADH + H+

                                         (Uronate dehydrogenase; UDH)
(2) D-Galacturonic acid + NAD+ + H2O → D-galactarate + NADH + H+

Kit size:                             * 100 assays (manual) / 1000 (microplate)
