beta-Galactosidase

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.).
