Overview
β-Galactosidase is a hydrolase enzyme catalyzing the hydrolysis of β-galactosides into monosaccharides. Produced via microbial fermentation, it typically features a molecular weight around 465 kDa and follows the general formula C24H38N10O13S for specific subunits. CAS No: 9001-90-3.
Application
- Dairy Industry: Hydrolyzing lactose in milk to produce lactose-free products for intolerant consumers.
- Biotechnology: Serving as a reporter gene marker (lacZ) in molecular cloning and blue-white screening.
- Pharmaceuticals: Assisting in the synthesis of galactoconjugates and diagnostic reagent development.
Precautions
- Storage: Maintain at -20°C or 2-8°C to preserve enzymatic activity; avoid repeated freeze-thaw cycles.
- Safety: Handle with standard PPE to prevent inhalation of dust particles; avoid direct skin contact.
- Usage: Not intended for direct human consumption without formulation; strictly regulated in clinical diagnostics.
