Triple-labeled immunofluorescence image of Normal Rat Kidney cells. Red staining corresponds to the focal adhesion protein paxillin. The actin cytoskeleton is labeled in green and the nuclei are stained blue. Paxillin is a multi-domain adapter protein that provides an important link between the actin cytoskeleton and transmembrane integrin receptors.
