Streptavidin is a bacterially derived biotin-binding protein that reportedly exhibits less nonspecific binding than does avidin. Allophycocyanin is an intensely bright phycobiliprotein with a broad absorption profile that peaks at ~650 nm, and a fluorescence emission maximum of ~660 nm. Our streptavidin allophycocyanin conjugate *premium grade* is a further fractionation of our S-868 product, intended especially for applications that benefit from additional purity.
