Lyophilized. Dialyzed. Also containing hemicellulase, cellulase, pectinesterase and xylanase activities.
Native protein chromatographically purified from Aspergillus niger
>=20 units per mg dry weight. One Unit releases 1 umole of D-galacturonic acid from polygalacturonic acid per minute at 37°C, pH 5.0.
Pectinase Assay; Plant protoplast isolation.
Store at 4°C on dry atmosphere.
Pectinase is extremely hydroscopic. If not using entire bottle at once, weigh into single-use aliquots on arrival and store tightly covered and dessicated, at 4°C. Material is very hygroscopic and can become tacky and difficult to weigh if exposed to moisture.
Pectinase is a multi-component enzymes complex that break down pectin, a polysaccharide substrate that is found in the cell walls of plants.
