N-(m-PEG4)-N'-(PEG2-acid)-Cy5
blur_circular Chemical Specifications
description Product Description
This compound is widely utilized in bioconjugation and labeling applications, particularly in biomedical research. Its structure, featuring PEG linkers and a Cy5 fluorophore, makes it highly suitable for creating stable, water-soluble conjugates with biomolecules like proteins, peptides, and antibodies. The PEG moieties enhance solubility and reduce immunogenicity, while the Cy5 dye allows for sensitive fluorescence detection in imaging and diagnostic assays. It is commonly employed in fluorescence microscopy, flow cytometry, and in vivo imaging to track cellular processes, protein interactions, and drug delivery systems. Additionally, its acid group enables easy covalent attachment to amine-containing molecules, facilitating the development of targeted probes and therapeutics.
