Alexa647-PEG-Lys-β-Ala

Alexa647-PEG-Lys-β-Ala is a structurally modified molecule that may be used for antibody, peptide, or small molecule drug conjugation. It combines fluorescent labeling (Alexa647), polyethylene glycol chains (PEG), and linker arms containing lysine and β-alanine to enhance the solubility, stability, and biocompatibility of the label.

Alexa Fluor 647 (AF647) is a far-infrared fluorescent dye widely used in biological labeling and imaging, with high brightness, strong light stability, and good water solubility, suitable for covalent labeling of various biomolecules.
