Vari Fluor 488-Streptavidin

Description

Vari Fluor 488-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. Ex/Em=490 nm/515 nm.
