Fluorescent Labeling

Fluorescent labeling is the process of combining fluorescent dyes with functional groups contained in biomolecules so that they can be visualized by fluorescent imaging. Fluorescent labels have many advantages because they are highly sensitive, long-term stable, and do not interfere with the function of the target molecule even at low concentrations. Targeted imaging of labeled cells can track them in vitro and in vivo. Using different fluorophores in the same sample can also observe multiple molecules at the same time. The most commonly used fluorophores are fluorescein isothiocyanate (FITC), rhodamine derivatives (TRITC), coumarin, and cyanine. These synthetic organic dyes are used to label biomolecules such as proteins, peptides, antibodies, nucleic acids, bacteria or yeast. Naturally occurring fluorescent dyes, such as green fluorescent protein (GFP), can also be used to genetically label living cells.

Fluorescent labeling technology

Chemical labeling technology: Fluorophores dock to the target molecule through chemical modification (covalent or non-covalent binding). Chemical labeling methods have many advantages because they are robust, easy to perform, and very effective, and are suitable for a wide range of fluorophores. They are more suitable for in vitro research rather than in vivo research.

Enzymatic labeling technology: Enzymatic reactions can be used for rapid, efficient and selective labeling in vivo and in vitro, and can be used to target proteins or whole cells.

Peptide/protein labeling: This technique is also easy to implement and can be used to study different sites of a single protein according to the specificity of the peptide tag.

Gene labeling: Gene tagging can be achieved by using fluorescent dye-labeled protein domains, small peptides or single amino acids. These amino acids can be specifically attached along chromosomes in the body. This method allows the detection of chromosomal abnormalities, such as deletions or duplications.
