Description

Chloramphenicol 1-o-β-D-Galactopyranoside is a specialized biochemical reagent, a galactosylated derivative of the antibiotic chloramphenicol. This compound is primarily valued as a critical substrate for the detection and assay of β-galactosidase enzyme activity. It is essential for research and development laboratories in the pharmaceutical, biotechnology, and diagnostic sectors, where precise enzymatic analysis is required for drug discovery, genetic engineering, and diagnostic kit development.

Application

• Enzymatic Substrate for β-Galactosidase: Used as a chromogenic or fluorogenic substrate in assays to measure β-galactosidase activity, a common reporter gene in molecular biology.
• Microbiological Research: Employed in studies involving gene expression regulation, particularly in systems like the Lac operon in E. coli.
• Diagnostic Reagent Manufacturing: A key component in the formulation of kits for clinical diagnostics and research to detect enzymatic activity.
• Pharmaceutical Development: Used in high-throughput screening (HTS) platforms during drug discovery to identify modulators of gene expression or enzyme function.
• Biochemical Research: Serves as a tool compound for studying glycosidase mechanisms and for developing novel biochemical pathways.

Quality Control

Our Chloramphenicol 1-o-β-D-Galactopyranoside is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency suitable for sensitive research applications. All products undergo rigorous analytical testing, including HPLC for purity and identity confirmation. A Certificate of Analysis (COA) detailing specific lot results is provided with each shipment to guarantee compliance with your research specifications.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and performance. For long-term storage, consider desiccants.
