:Neutral Red
Description:
Neutral Red is a synthetic dye and a pH indicator, commonly used in biological and chemical applications. It is characterized by its ability to change color in response to pH variations, typically transitioning from red in acidic conditions to yellow in neutral to alkaline environments. The compound is soluble in water and exhibits a maximum absorption wavelength in the visible spectrum, making it useful for staining cells in microscopy and histology. Neutral Red is often employed in cell viability assays, as it can penetrate living cells and accumulate in lysosomes, allowing researchers to assess cell health and proliferation. Additionally, it has applications in microbiology for differentiating between viable and non-viable cells. The substance is generally considered safe for laboratory use, although appropriate safety measures should be taken to avoid exposure. Its chemical structure includes a phenolic group, contributing to its staining properties and interaction with biological tissues. Overall, Neutral Red is a versatile tool in both research and educational settings.
