What is Flow Cytometry (FACS Analysis)? Written/Edited by Dr. Stefan Pellenz, PhD. Originally developed in the late 1960s, flow cytometry is a popular analytical cell-biology technique that utilizes light to count and profile cells in a heterogenous fluid mixture.
FACS Analysis. Flow cytometry is a technology that simultaneously measures and then analyzes multiple physical characteristics of single particles, usually cells, as they flow in a fluid stream through a beam of light. The properties measured include a particle’s relative size, relative granularity or internal complexity, and relative ...
Dr. Steffen Schmitt explains the principles of FACS and describes the basic components of a droplet cell sorter. He gives advice on optimizing the yield, purity, recovery time, and viability of isolated cells.
Fluorescence-activated cell sorting (FACS) of live cells separates a population of cells into subpopulations based on fluorescent labeling. Sorting involves more complex mechanisms in the flow cytometer compared to a non-sorting analysis.
Fluorescence-activated cell sorting is an advanced variant of flow cytometry that leverages fluorescent labels to sort and analyze cells, enabling researchers to isolate distinct populations with precision. It is frequently used in hematopoiesis, oncology, and immunotherapy.
FACS (Fluorescence-Activated Cell Sorting) is a specialized type of flow cytometry that sorts a heterogeneous mixture of cells based upon the specific light scattering and fluorescent characteristics of each cell.
Analysis: for best results, analyze the cells on the flow cytometer as soon as possible. We recommend analysis on the same day. For extended storage (16 hr) as well as for greater flexibility in planning time on the cytometer, resuspend cells in 1-4% paraformaldehyde to prevent deterioration.
