All KU dyes are available as 1 mg and 5 mg dry or in DMSO. Please quote the product number listed below when ordering. Back to catalogue.

KU450 is one of the few high brightness dye in blue. It is available in a range of reactive forms. The nature of the dye and the rather rigid linkers allows it to be used in polarisation based experiments.

KU450 is ideal as a substitute for fluorescein and the low intensity dyes in the blue.
