FLOW CYTOMETRY Flow cytometry is a procedure used for measuring multiple cellular and fluorescent properties of cells when they flow as a single cell suspension through a laser beam by a specialized instrument called as a flow cytometer. Flow cytometry can analyze numerous cells in a short time and…
Fluorescence A fluorochrome absorbs light energy and emits excess energy in the form of photon light (fluorescence). Fluorescence is the property of molecules to absorb light at one wavelength and emit light at a longer wavelength. The fluorescent dyes commonly used in flow cytometry are fluorescein isothiocyanate (FITC) and…
Leukemias and lympomas: Immunophenotyping (evaluation of cell surface markers), diagnosis, detection of minimal residual disease, and to identify prognostically important subgroups. Paroxysmal nocturnal hemoglobinuria: Deficiency of CD 55 and CD 59. Hematopoietic stem cell transplantation: Enumeration of CD34+ stem cells. Feto-maternal hemorrhage: Detection and quantitation of foetal hemoglobin in maternal…
The first fluorescence-based flow cytometry device (ICP 11) was developed in 1968 by Wolfgang Göhde from the University of Münster, Germany and first commercialized in 1968/69 by German developer and manufacturer Partec through Phywe AG in Göttingen. At that time, absorption methods were still widely favored by other scientists over…
