Application of OH-PEG-FITC Hydroxy-polyethylene glycol-fluorescein MW:2000 Cell labeling Fluorescent probes Nanoparticles

OH-PEG-FITC is a compound consisting of hydroxypolyethylene glycol (OH-PEG) and FITC (fluorescent isomer). It has a wide range of applications in biomedical and biochemical fields.

A common application is the use of OH-PEG-FITC as a cellular marker, where OH-PEG-FITC reacts with the carboxyl or amine groups on the cell surface to achieve cell labeling. For example, researchers can add OH-PEG-FITC to the cell culture medium, and the cells will actively take up OH-PEG-FITC and internalize it, thus achieving fluorescent labeling of the cells. Such labeling can be used for cell tracking, cell migration and cell interaction studies.

Another application is the use of OH-PEG-FITC as a fluorescent probe. OH-PEG-FITC can bind to specific biomolecules to form fluorescently labeled molecular probes that can be used to detect and monitor the presence of and changes in target molecules. For example, researchers can bind OH-PEG-FITC to antibodies, nucleic acids, or proteins to form fluorescently labeled antibody, nucleic acid, or protein probes for the detection and quantitative analysis of specific molecules.

In addition, OH-PEG-FITC can be used to prepare fluorescently labeled nanoparticles. By reacting OH-PEG-FITC with the carboxyl or amine groups on the surface of the nanoparticles, the FITC fluorescent dye can be immobilized on the nanoparticles, thus realizing fluorescent labeling of the nanoparticles. This labeling can be used for nanoparticle tracking and imaging, for example, in the fields of biosensing, drug delivery, and intracellular imaging.

In summary, OH-PEG-FITC has a wide range of applications in cell labeling, fluorescent probing and nanoparticle labeling. These applications can help researchers achieve fluorescent labeling of cells and molecules, detection and quantitative analysis of specific molecules, and tracking and imaging of nanoparticles.
