Fluorochromes are fluorescent dyes that are used in microscopy and flow cytometry to label biological molecules. They have various applications in research, diagnostics, and medical imaging. The term "Fluorochromes" can be replaced with synonyms such as fluorescence probes, fluorescent labels, fluorescent dyes, or fluorescent tags. Each term refers to specific types of molecules that emit light when excited with a suitable wavelength of light. The choice of the fluorochrome depends on the specific application and the type of biological target. The use of different fluorochromes enables the visualization of multiple biological molecules simultaneously, leading to new insights in various fields of biology.
