Immunostaining thin layer chromatograms TLC is a very sensitive detection technique of functionally active carbohydrate ligands of protein receptors. Carbohydrate structures are detected in glycolipids from complex mixtures of molecules extracted from the relevant target tissue. Proteins analyzed can be antibodies, chimeric Ig proteins, selectins, lectins, toxins, and other carbohydrate binding proteins. John L.

Early embryos (0-17 hours or until cuticle formation) are treated with a mixture of organic solvents, formaldehyde, and alcohols, as described here. The cuticles of late-stage embryos are usually opened by sonication. Tissues from more advanced stages of development are normally dissected by hand and then fixed and stained in a standard paraformaldehyde/detergent combination - [Read Preparing Early Whole-Mount Drosophila Embryos for Immunostaining Protocol]
Frozen tissue sections show good preservation of tissue structure and antigens. The principle disadvantages of using them in immunostaining are that the specimens must be stored frozen, and a special microtome, known as a cryostat, is required. Also, many clinical specimens are not available in this form, and most classic histological descriptions of tissue structure and pathology are based on the use of paraffin-embedded sections of formalin-fixed material. - [Read Preparing Frozen Tissue Sections for Immunostaining Protocol]
Early and late embryos are treated with a mixture of organic solvents, formaldehyde, and alcohols. The cuticles of late-stage embryos (17-22 hours or until hatching) are usually opened by sonication, as described here. Tissues from later stages of development are normally dissected by hand and then fixed and stained in a standard paraformaldehyde/detergent combination. - [Read Preparing Late Whole-Mount Drosophila Embryos for Immunostaining Protocol]
Most histological studies are carried out on paraformaldehyde-fixed, paraffin-embedded tissue samples. Therefore, there is an extensive atlas of most tissues and organs prepared from these sources, and comparing the location of antigens to these data is immediately informative. The fixation and embedding procedures are harsh, however, and many antigens are not well preserved. - [Read Preparing Paraffin Tissue Sections for Immunostaining Protocol]
