Fluorescence-activated cell sorting (FACS), sometimes called fluorescence-assisted cell sorting, is a specialized type of flow cytometry that uses fluorescent markers to target and isolate cell groups. …

A fluorescence microscope is much the same as a conventional light microscope with added features to enhance its capabilities.  This fluorescent species in turn emits a …

Fluorescence in situ hybridization (FISH) is a laboratory technique for detecting and locating a specific DNA sequence on a chromosome. The technique relies on exposing chromosomes …

Fluorescence spectroscopy uses a beam of light that excites the electrons in molecules of certain compounds, and causes them to emit light. That light is directed …

Flow Cytometry is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. In this process, a sample …

Fluorescence-activated cell sorting (FACS) is a technique to purify specific cell populations based on phenotypes detected by flow cytometry. This method enables researchers to better understand …

In epifluorescence microscopy, a parallel beam of light is passed directly upwards through the sample, maximizing the amount of illumination. This is also referred to as …

The entire electromagnetic spectrum, from the lowest to the highest frequency.  includes all radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, etc. …

X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. An X-ray, or, much less commonly, X-radiation, is a …

A gamma ray (g) is a packet of electromagnetic energy (photon) emitted by the nucleus of some radionuclides following radioactive decay. Gamma photons are the most energetic …
