Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
In the realm of molecular biology and biochemistry, understanding enzyme activity is paramount. One of the most commonly studied enzymes is β-galactosidase, and its activity is often quantified using specific substrates. Among these, 2-Nitrophenyl Beta-D-Galactopyranoside (often abbreviated as o-NPG or 2-NPG) stands out as a crucial chromogenic substrate. As a leading manufacturer and supplier of biochemical reagents in China, we are committed to providing researchers with the high-purity materials needed for reliable experimental outcomes.
What is β-Galactosidase and Why Assay It?
β-Galactosidase is an enzyme that catalyzes the hydrolysis of β-galactosides into their constituent monosaccharides. Its importance spans various biological processes. In molecular biology, it's famously used as a reporter gene in cloning experiments to indicate successful gene insertion. In diagnostics, its presence or absence can signal specific conditions. Therefore, accurately measuring its activity is vital.
The Role of 2-Nitrophenyl Beta-D-Galactopyranoside (CAS 369-07-3)
2-Nitrophenyl Beta-D-Galactopyranoside (CAS 369-07-3) is a synthetic substrate designed to react specifically with β-galactosidase. When the enzyme cleaves the glycosidic bond in 2-NPG, it liberates p-nitrophenol, which has a distinct yellow color. This color change is directly proportional to the amount of active β-galactosidase present, making it an excellent tool for colorimetric assays. Its chemical structure, appearance as a white powder, and high purity (often specified as ≥97% or ≥99%) ensure consistent and reproducible results for researchers worldwide.
