Preparation: cryostat-sectioned tissue; formaldehyde fixed tissue; embedded tissue; methylcellulose embedded Relation to intact cell: sectioned tissue Item type: recorded image Imaging mode: transmission electron microscopy (TEM) Parameter imaged: electron density Source of contrast: differences in adsorption or binding of stain; distribution of a specific protein Visualization methods: gold; uranyl salt; primary antibody plus labeled secondary antibody Processing history: unprocessed raw data Data qualification: Raw;spatialmeasurements ... : Tissue was processed for immunoelectron microscopy using a modified Tokuyasu method. Briefly, minced tissue was fixed in 4% paraformaldehyde containing 5% sucrose and 100 mM HEPES and infiltrated with PBS containing 2.1 M sucrose over 10 h, with repeated solution changes. Fixed tissue was transferred to an aluminum cryosectioning stub (Ted Pella, Inc., Redding, CA) and immediately frozen in liquid nitrogen. Semithin (90 nm) cryosections were cut at -110C with an UltraCut UCT/FCS cryomicrotome (Leica), using a diamond knife (Diatome) and transferred to a Formvar-coated, carbon-coated, glow-discharged 100-mesh copper-rhodium electron microscopy grid. Following blocking of nonspecific antibody binding sites with 10% calf serum in PBS, the sections were labeled by incubation with an antibody to TGN38 (2F7, mouse monoclonal) followed by colloidal gold-conjugated secondary antibody (10 nm anti-mouse; Ted Pella Inc., Redding, CA) and then negatively stained and embedded with 1% uranyl acetate, 1% methylcellulose in ...
