Description: o-Nitrophenyl-β-D-galactoside is a cell culture component for molecular genetics. It is chromogenic substrate for b-galactosidase and hence is useful in the detection of lacZ activity.

Supplier: MP Biomedicals

Description: p-Nitrophenyl-alpha-D-galactopyranoside is used as a substrate for α-galactosidase.

Catalog Number: (786-651)

Supplier: G-Biosciences

Description: β-Galactosidase assay is for determining the β-galactosidase activity in the lysates of cells transfected with a β-galactosidase expression construct. It uses chlorophenol red-β-D-galactopyranoside (CPRG), which is up to 10 times more sensitive than the classic O-nitrophenyl-β-D-galactopyranoside (ONPG) β-Galactosidase assays. This increased sensitivity makes it simpler to measure β-galactosidase activity in cells that are difficult to transfect or have low β-galactosidase activity expression. β-Galactosidase activity is measured using a spectrophotometer or a microplate reader to determine the amount of substrate converted at 570 to 595 nm.

Supplier: MP Biomedicals

Description: Inhibitors: p-Chloromercuribenzoate, lodoacetamide, heavy metal ions (Zn²⁺, Fe²⁺, Zn²⁺, Cd²⁺, Cu²⁺, Pb²⁺, Ag⁺, Hg²⁺), Ionic Detergents (SDS, DAC, etc.). Contaminants: The preparation is practically free from other glycosidases (a-galactosidase, a-,b-glucosidase, a-,b-mannosidase, etc.) and proteinase. Principle: o-Nitrophenyl-b-D-galactopyranoside (ONPG) b-galactosidase > <i>o</i>-Nitrophenol (ONP) +D-Galactose. The appearance of o-nitrophenol is measured at 410 nm by spectrophotemetry. Thermal stability: below 50 °C (pH 7,3; 15 min) (Lit.), Optimum Temperature: 50 to 55 °C (Lit.).
