Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
In the intricate world of biochemical analysis and diagnostics, the selection of the right substrate is paramount for achieving accurate and reliable results. Chromogenic substrates, in particular, play a pivotal role by providing a visual cue—color—that indicates the presence and activity of specific enzymes. Among the widely used compounds in this category is 2-Nitrophenyl Beta-D-Galactopyranoside (CAS 369-07-3), a key player in assays involving β-galactosidase. As a leading manufacturer and supplier based in China, we are dedicated to providing high-quality chromogenic substrates to the global scientific community.
What is a Chromogenic Substrate?
A chromogenic substrate is a substance that reacts with a specific enzyme to produce a colored product. This color change allows for the easy detection and quantification of enzyme activity without the need for complex detection equipment, making assays more accessible and cost-effective. The specificity of the substrate ensures that the observed color is a direct result of the target enzyme's action, minimizing interference from other biological components.
2-Nitrophenyl Beta-D-Galactopyranoside: A Versatile Tool
2-Nitrophenyl Beta-D-Galactopyranoside (2-NPG) is a prime example of a successful chromogenic substrate. It is specifically designed to be hydrolyzed by the enzyme β-galactosidase. Upon cleavage, the β-galactosidase enzyme releases a p-nitrophenol moiety, which, in an alkaline environment, turns yellow. The intensity of this yellow color is directly proportional to the amount of β-galactosidase present. This property makes 2-NPG indispensable for:
For researchers and manufacturers, the ability to buy 2-Nitrophenyl Beta-D-Galactopyranoside with high purity (≥97% or higher) and consistent quality is essential.
