Physicochemical properties (the following information is for reference only):White or light yellow powder,. Odorless, slightly sweet. An enzyme that hydrolyzes lactose to glucose and galactose. Generally refers to the ability to β- An enzyme that hydrolyzes galactosides to galactose and glycosides. It is a chaotic liquid (mostly dissolved) in water and insoluble in ethanol and acetone. The pH range is 5.5 ~ 9.5 (25 ℃, 20HR), the optimum pH is 7.0, and the optimum action temperature is 50 ℃. During activity measurement, the powder was dissolved into a transparent liquid with 100mm ph7.3 potassium phosphate buffer. Extracted from Escherichia coli.
Purpose: This product is only for scientific research and shall not be used for other purposes. (the following purposes are for reference only) β- Galactosidase can hydrolyze through β- A galactose residue attached to a monosaccharide, oligosaccharide, or glycopeptide by β-1 → 4 glycosidic bond. It is mainly used in enzyme-linked immunosorbent assay, coupled to the antibody as a marker. In addition, β- Galactosidase can also be used for sugar structure analysis, lactose detection and sodium ion detection.
