title: Imaging of immunogold labelled antigens on capping thymocytes by confocal reflection contrast scanning optical microscopy.
abstract: Confocal laser scanning optical microscopy (CLSM) in the reflection contrast mode has been used to image single 40 nm gold particles, and to study changes in the distribution of gold label associated with capping of the leukocyte sialoglycoprotein (LSGP) antigen on the surface of fixed rat thymocytes, labelled with the mouse monoclonal antibody W3/13 and a goat anti-mouse IgG immunogold conjugate. This imaging method has also been applied to live thymocytes labelled with gold-conjugated antibodies, to study the dynamics of the capping process.
