Detection of rare cells and circulating tumor cells using flow cytometric methods

27 Jan 2021

Circulating tumor cells (CTC) are rare cells shed from a solid tumor or metastases that circulate through the bloodstream. Detection of CTC poses a challenge because they are present at extremely low concentrations, as few as a couple CTC in several milliliters of blood, which contain up to 3 to 6 million cells per mL. To determine the sensitivity and accuracy of rare cell detection on the Agilent NovoCyte Quanteon flow cytometer, a tumor cell spiking assay was used in which a small number of cells from a tumor cell line was added to whole blood and detected by a cell surface stain.

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.
