An introduction to Performing Immunofluorescence Staining
Fluorescence detection is possible with use of fluorophore-conjugated antibodies, which emit light upon excitation via light of a shorter wavelength. The most commonly used fluorophores are fluorescein isothiocyanate (FITC) and tetramethylrhodamine isothiocyanate (TRITC).
Immunofluorescence- Definition, Principle, Types, Uses, Limitations
2022年3月1日 · Immunofluorescence is a type of assay performed on biological samples to detect specific antigens in any biological specimen or sample and vice-versa. The specificity of antibodies to their antigen is the base for immunofluorescence.

2023年9月1日 · Immunofluorescence assay (IFA) is a laboratory technique used for detecting and visualizing specific antigens or antibodies in biological samples. It combines the principles of both immunology and fluorescence microscopy to provide highly specific and sensitive results.
Antibodies 101: Introduction to Immunofluorescence - Addgene
2021年11月16日 · Immunofluorescence (IF), is an immunoassay that brings to light the cellular world. The technique allows you to ask questions like: “Where does my protein of interest live within a cell,” “Does this disease change the architecture of my cells,” or “How does this mutation impact the types of cells found in my tissue.”
Immunofluorescence Information | Thermo Fisher Scientific - US
Protein blocking equals specific antibody binding. Dye charge blocking means less non-specific binding. Every primary antibody must be optimized separately. There are many protocols available, and it is important to understand a "one size fits all" approach gives inferior results, as every antibody is slightly different.
ed secondary antibody (indirect detection). Either method allows the user to combine multiple fluorophores (multiplex analysis), making IF ideal for investigating protein co-localization, changes in subcellular localization, differential activation of proteins within a cell, identification of.
