Introduction To Flow Cytometry

FLOW CYTOMETRY ? extend Cytometry is the technology that measures properties of single particles and/or cells. ? Measures fluorescence, call forth up sprinkling, and other properties of particles and/or cells. ? Can provide correlated information that links different population profiles all base on single particles and/or cells abbreviation (hydro-dynamic focusing). What can Flow Cytometry do? ? Enumerate particles and/or cells in suspension. ? Determine biological from Non-biological samples. ? holy order life from dead cells. ? Evaluate 105 to 107 particles and/or cells in about one minute. ? Measure particles and/or cells recess as well as innate fluorescence or 2° fluorescence. ? potpourri single particles and/or cells for sub-sequent digest. ? Do advance multi-parameter analysis on complex data. What are the principles? ? Light sploshed by optical maser or arc lamp. ? Spec ific fluorescence detection. ? Hydro-dynamically focused stream of particles and/or cells. ? Electrostatic particles and/or cells separation for sorting. ? Multivariate data analysis capability. Definitions ? Flow Cytometry (cyto = cell) (metry = measurement). o Cyto is derived from the Greek kitos meaning labour as a cell or container.

From the same stalk go in the combining form cyto and the suffix cyte which withal denote a cell. o Metry; Greek metria, from metron measure. Indicating the process of scientific measurement. Technical Components ? catching Systems: o Photomultiplier Tubes (PMTs). o Diodes light scatter detectors. ? Illuminat! ion Systems: o Lasers. o Arc lamps. Concepts ? Light disseminate: o onwards Scatter roughly size for nearly particles and/or cells although it is a complex parameter 90° scatter shape, granularity, Polarized Scatter (birefringence) Structure. o Materials scatter light at wavelengths at which they do...If you want to buy off a full essay, order it on our website: OrderEssay.net
