Description

2,3,5-Triphenyltetrazolium Iodide is a vital organic salt widely used as a redox indicator and a critical reagent in biochemical assays. Its primary value lies in its ability to form a vivid, water-insoluble formazan dye upon reduction, making it an essential tool for detecting cellular metabolic activity. This compound is indispensable for researchers and quality control laboratories in the pharmaceutical, biotechnology, and life sciences sectors, particularly for applications like microbiological sterility testing and cell viability assays.

Application

• Microbiological Sterility Testing: A key component in culture media for the rapid visual detection of microbial growth, especially in pharmaceutical quality control.
• Cell Viability & Cytotoxicity Assays: Used in assays (e.g., MTT assay analogs) to measure mitochondrial activity in live cells.
• Biochemical Redox Indicator: Serves as an electron acceptor in enzymatic reactions to visualize dehydrogenase activity.
• Seed Viability Testing: Employed in agricultural research to assess the metabolic activity and germination potential of seeds.
• Histochemical Staining: Used in tissue sections to localize areas of metabolic activity or ischemic damage.
• Pharmaceutical Research: Utilized in drug discovery and development for screening compound effects on cell metabolism.
