B or T cells in suspension, adherent cells on chambered coverglass or chamberslides, cryostat sections of unfixed, OCT embedded tissue. Susan Anderson. - [Read Immunofluorescence / confocal microscopy]
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]
