Description

2-Phenylethyl-β-D-Thiogalactoside is a specialized thioglycoside compound widely used as a potent and specific inhibitor of β-galactosidase enzymes. This high-purity biochemical is critical for research and development in molecular biology and enzymology, where precise enzyme inhibition is required. It serves as an essential tool for scientists and manufacturers in the pharmaceutical, diagnostic, and life science research sectors.

Application

• Biochemical Research: A key reagent used as a specific, non-hydrolyzable inhibitor in studies of β-galactosidase enzyme kinetics and function.
• Molecular Biology: Employed in control experiments for gene expression assays (e.g., lacZ reporter systems) to confirm specific enzymatic activity.
• Diagnostic Kit Development: Used in the formulation and quality control of diagnostic assays that utilize β-galactosidase as a reporter enzyme.
• Pharmaceutical Screening: Serves as a reference standard and inhibitor in high-throughput screening for drug discovery programs targeting glycosidase enzymes.
• Enzyme Purification: Applied in affinity chromatography for the purification of recombinant β-galactosidase and related proteins.
• Cell Biology Studies: Utilized to inhibit endogenous β-galactosidase activity in cell lysates and tissue samples to prevent background signal.

Quality Control

Our 2-Phenylethyl-β-D-Thiogalactoside is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) with detailed specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to maintain product integrity and prevent degradation.
