Tetrazoliums

Santa Cruz Biotechnology now offers a broad range of Tetrazoliums for use in various applications. Tetrazoliums are a class of organic compounds characterized by their unique five-membered ring structure containing four nitrogen atoms. These compounds are widely utilized in scientific research, particularly in biochemical and cell biology studies, due to their role as redox indicators. Tetrazoliums are used in various assays to measure cell viability, enzyme activity, and metabolic processes. When reduced, they form intensely colored formazan products, providing a visual indication of biological activity. This property makes Tetrazoliums invaluable in experiments involving cellular respiration, mitochondrial function, and microbial growth. Additionally, their versatility extends to use in electron microscopy, where they can help localize enzymatic activity within tissues and cells. The ease of use and sensitivity of Tetrazolium-based assays have made them a staple in research laboratories, offering a reliable means to quantify and visualize biological processes.
