Single-cell analysis has generated a wealth of information in cell population studies. The characteristics of cells in a heterogeneous population can be analyzed without the loss of information that would result from averaging the population as a whole.
Until now, most single-cell analysis has been focused on the surface properties since limited markers exist that can penetrate the plasma membrane into the cytosol and allow measurement of the cellular contents in single cells. Most cytosolic components can only be measured after disruption of the plasma membrane and report on the composition of the population as a whole rather than on individual cells in a heterogeneous cell population.
Using a multi-disciplinary approach, combining biomedical science and nanotechnology developed by micromechanical engineering, the Microfluidics Flow Lysometer (MFL) team is developing a novel technique, flow-lysometry, which measures cytosolic components of single cells.
The team envisions that this technology can be applied to various types of cells measuring many different cytosolic components including antibodies, RNA levels and enzyme production.
The flow-lysometry technology when combined with commercially available flowcytometer capabilities will be capable of correlating individual cell morphology and surface characteristics with the cell's internal biochemistry.
Flow cytometry is currently used in numerous applications in basic research, clinical research, drug discovery and clinical diagnostics testing. With the extension of flow-lysometry, this proprietary technology provides a more robust cell analysis capability.
