Flow Cytometry: Using light to count and profile cells

Originally developed in the late 1960s, flow cytometry is an analytical cell-biology technique that utilizes light to count and profile cells in a heterogenous fluid mixture. Flow cytometry is a particularly powerful method because it allows a researcher to rapidly, accurately, and simply collect data related to many parameters from a heterogeneous fluid mixture containing live cells.

To learn about flow-cytometry, visit the antibodies-online resource pageWhat is Flow Cytometry/FACS?” This valuable digital resource contains information on the fundamental basis of flow cytometric analysis. Topics covered include: “What is the difference between conventional flow cytometry and FACS?”, “What does flow cytometry data look like?” and “What does ‘gating’ do in a flow cytometry experiment?”
