TAMRA-Azide-PEG-Biotin(CAT: I014699) is a multifunctional reagent combining three key functional groups: TAMRA (a fluorescent dye), azide, and biotin. The TAMRA dye enables fluorescence-based detection in imaging and analytical applications. The azide group facilitates copper-catalyzed azide-alkyne cycloaddition (Click Chemistry) for conjugation with alkyne-functionalized molecules. Biotin allows for high-affinity binding to streptavidin, enabling purification, enrichment, or detection in biochemical assays. The PEG spacer enhances solubility and reduces nonspecific interactions. TAMRA-Azide-PEG-Biotin is widely used in proteomics, molecular biology, and bioimaging for labeling, tracking, and studying biomolecular interactions.
