title: Comparative study using scanning electron techniques for imaging of micro-architecture and antigen appearance.
abstract: We have used various scanning electron microscopy technologies for the analysis of structures and the appearance of antigen on eukaryotic cells. Various scanning electron microscopy including conventional scanning electron microscopy, high-resolution scanning electron microscopy and environmental scanning electron microscopy applied for cell surface analysis allow obtaining sub-micrometre surface features on cell membranes. We used cell systems for imaging along with molecular localization of a cell surface antigen, SVEP1 protein. SVEP1 was studied using the immuno-gold technique for the identification of cell surface features and protein localization. We used an antibody to SVEP1 molecule that was labelled with secondary antibody conjugated with gold particles. The comparison between scanning electron methods enabled the visualization of surface structures and the molecular imaging for the distribution of SVEP1.
