Tracing protein receptors on cells

Abstract:
Researchers from the Old Dominion University in Virginia, US, have developed a method of detecting individual protein receptors on the surface of cells that induce cellular response.

The research, published as an early view article in the journal Analytical Chemistry used nanoparticle optical biosensors conjugated to Immunoglobulin G (IgG) to detect and track the activity of individual cell receptors for a period of hours.

Activation of these receptors initiates the complex communication system within a cell, coordinating cell development, tissue repair and immunity responses.
