Description of the practical activities. Preparation of histological slides: fixation, inclusion, paraffin section preparation, staining of samples and observation with optical microscope. Immunohistochemical method: the reaction ABC immunoperoxidase. Sample preparation for fluorescence microscopy: observation under a fluorescence microscope and confocal laser scanning microscope. Sample preparation for transmission electron microscopy: fixation, dehydration, resin embedding, thin sectioning, negative and positive staining. TEM observation. The immunogold labelling: sample preparation and observation. The scanning electron microscope: sample preparation and observation. Elemental microanalysis: sample preparation and observation. The practical activities will be carried out at the Zoology and CGA laboratories.
