Description

Neutral Red Iodide is a vital organic salt and biological stain, primarily recognized for its role as a redox indicator and vital dye in cell viability assays. Its value lies in its selective uptake and accumulation in the lysosomes of living cells, making it a critical tool for distinguishing between viable and non-viable cell populations. This compound is essential for researchers and quality control laboratories in the biotechnology, pharmaceutical, and life sciences sectors, where accurate cell culture assessment is paramount.

Application

• Cell Viability and Cytotoxicity Testing: Used in the Neutral Red Uptake (NRU) assay to assess cell health and screen for chemical toxicity.
• Lysosomal Function Marker: Acts as a probe for studying lysosomal activity and pH within living cells.
• Microbiological Staining: Employed as a vital stain in microbiology to differentiate live bacterial cells.
• Redox Indicator: Functions as an oxidation-reduction indicator in certain analytical chemistry applications.
• Histological Staining: Used in specific tissue staining protocols for microscopic examination.
• Research Reagent: A key component in kits and protocols for in vitro toxicology and biomedical research.
