Übersicht

β-Galactose Dehydrogenase is a selective catalyst for β-galactose. Under pH 8.6 conditions, β-galactose dehydrogenase catalyzes the oxidation of β-galactose, produced by the hydrolysis of lactose by β-galactosidase, with nicotinamide adenine dinucleotide (NAD) to produce reduced nicotinamide adenine dinucleotide (NADH). β-galactose dehydrogenase specifically mediates this oxidation reaction for the quantitative detection of the substrate, used in the analysis of lactose concentration in samples such as breast milk.

Häufig gestellte Fragen

What does Bioactive mean?

Bioactive indicates that the product has been processed and tested for biological and biochemical applications. Specifications may include endotoxin limits, microbial controls, sterility, low DNase/RNase/protease activity, and verified biological activity where relevant.

What does Recombinant mean?

Recombinant is a defined analytical purity tier suitable for workflows requiring a specific validated property. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Recombinant is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
