Flow Cytometry is an effective tool to analyze more than one parameter on an individual cell basis. Cell populations may identify the use of a combination of antigens both at the surface and intracellularly. There are numerous practical packages often utilized by immunologists consisting of immunophenotyping, analyzing intracellular cytokine production, cellular proliferation, evaluating the cellular viability and evaluation of cell cycle, stem cells, rare events and fluorescent proteins. Moreover, the Cell sorting primarily based on flow Cytometry is used to split cells into populations of interest.
Let’s have a look at what is Flow Cytometry
Flow Cytometry technology depends on the measurement of fluorescence related to cells, generally for immunological detection of monoclonal antibodies coupled to fluorochromes e.g. dilution of fluorescent dyes along with CFSE for the duration of proliferation, or FITC anti-CD3.
Necessarily Flow cytometers run cells beyond a laser a single cell at a time discover fluorescence and mild scattered from the cell and file this record for the next analysis. A range of lasers are generally used and are named after the emission wavelength or color: 360nm (UV laser), 633nm (Red HeNe laser), 405nm (Violet laser), 488nm (Blue argon laser), 532nm (Green laser), etc.
Fluorochromes which can be conversely delighted on only one of the lasers are to be had with new fluorochromes and dual-conjugated i.e. ‘tandem’ dyes being communally produced.
Furthermore, some common fluorochromesare APC, FITC, PE, PerCP, and Pacific Blue, typically used tandem fluorochromes comprise PC-Cy7 and PerCP-Cy5.5
Flow Cytometry for the immunologist
The fact is that the Flow Cytometry Immunology has several applications, comprising tracking the expansion of antigen-specific T cells by executing a large total volume of cells to find out a small percentage of particular cells. The increased information gets from staining for multitude antigenic markers.
For instance: at the time of investigating regulatory T cells, it may be efficient to stain for a volume of markers with a panel like CD4-PerCP, CD3-PeCy7, CD39-FITC, Foxp3-PE, and CD25-APC.
Moreover, it is significant to have the accurate controls to establish up the flow cytometer and accurately compensate for any overlap in the emission of every one of the fluorochromes. Moreover, these controls are the single color, unstained cells, and Fluorescence Conjugated minus one where all antibodies in the panel are combined with cells, eliminating a single antibody in turn.
