FITC-PEG-Alkyne Isothiocyanate-Polyethylene Glycol-Alkyne MW:1000 click reaction Molecular labeling Biosensing Nanotechnology

FITC-PEG-Alkyne is a fluorescently labeled polyethylene glycol (PEG) compound that has a wide range of applications in biochemical and biomedical research. This compound consists of three main components: fluorescent isothiocyanate (FITC), polyethylene glycol (PEG), and an alkyne group.

FITC is a commonly used fluorescent probe that is widely used in fluorescence microscopy, flow cytometry, and other techniques. Its fluorescence emission is in the green light region, allowing the compound to produce high-contrast images in many biological tissues and cells.

PEG is an extremely biocompatible polymer that improves drug solubility, extends the half-life of drugs in the body, reduces immunogenicity and increases drug stability.

An alkyne group is a chemical group that can be linked to another functionalized compound by click chemistry.

Here are some applications of FITC-PEG-Alkyne:

1. Biomarkers: FITC-PEG-Alkyne can be used to label a variety of biomolecules such as proteins, peptides, antibodies, etc. for detection and tracking in fluorescence microscopy or flow cytometry.
