Methylene Blue Trihydrate (25g) is a vital biological staining dye widely used in microscopy and microbiology. This powerful reagent is ideal for staining animal cells, bacterial cultures, and various biological tissues. Methylene Blue is used in histological studies to identify cell structures such as the nucleus, mitochondria, and other intracellular components. It also serves as a key component in vital staining techniques, which allows researchers to assess the viability of cells. The 25g size is ideal for small-scale applications, ensuring high-quality staining with minimal reagent waste. This dye is also used in diagnostic labs for microbial identification and biological research.
