Biological Stains and Indicators
Biological stains and indicators are essential tools in microscopy, cell biology, and various biochemical assays. They help visualize, differentiate, and identify biological tissues, cells, and molecular components.
Biological stains are dyes used to enhance the contrast of biological specimens viewed under a microscope. They can bind to specific cellular components, making them visible and distinguishable.
Biological indicators are substances used to detect, quantify, or monitor biological processes, often by changing color or fluorescence.
