| 别名 | ONPG;邻硝基苯-β-D-吡喃半乳糖苷;o-Nitrophenyl β-D-galactopyranosideONPG | 
		
			| 产品介绍 | 溶于水、甲醇,水中溶解度可达15mg/ml。有吸湿性。 | 
		
			| 用途 | 用于检测β-半乳糖苷酶(β-galactosidase)活性,是β-半乳糖苷酶的显色底物。经β-半乳糖苷酶催化后可产生黄色产物,在410-420nm波长可以检测吸光度。 | 
		
			| 生化机理 | β-galactosidase, breaks down lactose into galactose and glucose. β-Galactosidase is not lactose specific and can act on simple galactosides. 2-Nitrophenyl β-D-galactopyranoside hydrolysis results in the release of galactose and a yellow chromogenic compound. The test substrate does not depend on an induced or constitutive permease enzyme to enter the cell, therefore reactions are rapid and occur within a 24-hour period. |
