AF 594 streptavidin

AF 594 streptavidin is a bioconjugating agent. It consists of AF 594 and streptomycin, a streptomycin derivative of the red fluorescent dye AF 594. AF 594 has high fluorescence quantum yield and high photostability (Ex=594 nm, Em=615 nm). AF 594 streptavidin can be selectively conjugated to streptavidin-modified molecules via a streptomycin-modifying group for fluorescent labeling and spectroscopic analysis.
