Flow cytometry can be performed directly, using conjugated primary antibodies, or indirectly, using a conjugated secondary antibody to bind an unconjugated primary. Add the appropriate number of cells to be stained into a FACS tube or 15mL conical. Fluorescence activated cell sorting (FACS) of live cells separates a population of cells into sub-populations based on fluorescent labeling. The principle behind FACS is an antigen-antibody reaction, with the antibodies being fluorescently labelled. In its simplest application, it can count cells as each crosses the laser beam. Since exosomes are too small for direct FACS analysis, they must first be captured on a larger surface. Advantages: Can produce large quantities of identical antibody. In FACS (fluorescence assisted cell sorting), the characteristics of the cells determined in the flow cell may be used as a criteria to divert the cell to a collection chamber. (Use this buffer also for all washes until directed to use Sorting Buffer. Filter the cells through a 50‐μm cell strainer into a sterile flow cytometry tube.

Magnetic and size sorting received a rating of 8 because it has 98% accuracy, as stated above, and panning received a rating of 7 because, as mentioned above, it has between 97 and 98%. Thanks for posting, I knew some of the tricks, but not all of them. In additon to identifying the size and granularity of cells, flow cytometry provides cell phenotyping by using fluorescent-labeled antibodies directly against surface markers. m Monday through Friday. Flow Cytometry Optimization Following is a list of recommendations for optimizing the data in your flow cytometry experiments. (2000), chapter in In Living Color: Protocols in Flow Cytometry and Cell Sorting (R. Flow Cytometry (FACS) Service. The FC Lab has two analytical flow cytometers (FACS Calibur and FACSort) and one flow cytometer with sorting capability (FACS Vantage SE with fiber optics and Diva software operating system). 2 Fluorescent antibody staining to exclude stromal/vascular cells from adipocytes 290 3. Gulbranson,1 Eric M. Flow Cytometry - Isotype Controls. All incubations should be performed on ice and with minimal light exposure. Thus, what is flow cytometry? cyto = cell, metry = measurement, flow = cell suspension in motion. A reliable method for discrimination of background and authentic fluorescent signal is the use of a negative control antibody of the same isotype as the fluorophore-labeled primary or secondary antibody employed. DeMaggio, eds). A FACS machine is sometimes called a cell sorter.
