Cy5 Amine TFA(CAT: I040985) is a bright, far-red fluorescent dye featuring a primary amine (-NH₂) functional group, ideal for bioconjugation and labeling applications. This cyanine-based fluorophore exhibits strong far-red emission (~650 nm) with excellent photostability and water solubility, making it suitable for fluorescence microscopy, flow cytometry, and imaging assays. The trifluoroacetate (TFA) salt form enhances its stability and solubility for research applications. Cy5 Amine is widely used in protein, peptide, and oligonucleotide labeling, as well as fluorescence-based biosensing and cellular imaging. For research use only; not for human or clinical applications.
