Description of the hand-on activities.
Preparation of histological slides: fixation, embedding, 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. Laser microdissection of biological samples. 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 hands-on activities will be carried out at the Zoology and CGA laboratories.
