Abstract:
Immunofluorescence (IF), a form of immunohistochemistry (IHC) with specific applications, is commonly used for both basic research and clinical studies, including diagnostics, and involves visualizing the cellular distribution of target molecules (e.g., proteins, DNA, and small molecules) using a microscope capable of exciting and detecting fluorochrome compounds that emit light at specific, largely nonoverlapping wavelengths. The procedure for carrying out IF varies according to the tissue type and methods for processing and preparing tissue (e.g., fixative used to preserve tissue morphology and antigenicity). The protocol presented here provides a general guideline for multichannel IF staining using frozen embryonic mouse or chicken tissue sectioned on a cryostat. In general, the procedure involves the following: (1) fixing freshly dissected tissues in a 4 % paraformaldehyde solution buffered in the physiological pH range, (2) cryopreservation of tissue in a 30 % sucrose solution, (3) embedding and sectioning tissue in Optimal Cutting Temperature (OCT) matrix compound, (4) direct or indirect detection of the target antigen/s using fluorochrome-conjugated antibodies.
