Ultrathin Frozen Sections
A relatively simple method for obtaining ultrathin, frozen sections for electron microscopy has been developed. Tissues, cultured cells, and bacteria may be employed. They are fixed in 1.25-4% glutaraldehyde for 1-4 hr, are washed overnight in buffer at 3 degrees C, and are embedded in 20% thiolated gelatin or pure gelatin. Before sectioning they are partially dehydrated in 50% glycerol, frozen...

متن کاملUse of colloidal gold particles in double-labeling immunoelectron microscopy of ultrathin frozen tissue sections
Complexes of protein-A with 5 and 16 nm colloidal gold particles (PA/Au5 and PA/Au16) are presented as sensitive and clean immunoprobes for ultrathin frozen sections of slightly fixed tissue. The probes are suitable for indirect labeling and offer the opportunity to mark multiple sites. The best procedure for double labeling was to use the smaller probe first, i.e., antibody 1 - PA/Au5 - antibo...
متن کاملImproved Techniques for the Preparation of Ultrathin Frozen Sections
Ultrathin frozen sections of biological tissues for electron microscopy provide certain advantages in cytochemical studies in which the penetration of cells by large molecules is necessary and in morphological studies of cellular constituents which are dissolved by the reagents employed in routine plastic embedding . The recent introduction of several types of commercially available cryo-ultram...
