Vari Fluor 647-Streptavidin

Vari Fluor 647-Streptavidin is a dye marker of Vari Fluor-streptavidin consisting of labeling streptavidin with a Vari Fluor series of fluorescent probes. Streptavidin is a high-affinity tetramer protein, each tetramer consisting of four identical streptavidin subunits. Streptavidin binds to biotin specifically via a reversible non-covalent effect. Streptavidin can achieve rapid and efficient detection of biotin markers, and is often used in immunofluorescence (IF), enzyme-linked immunosorbent assay (ELISA), immunohistochemical staining (IFH), in situ hybridization (ISH) and other experiments.
