Diphenylterazine is a bioluminescence compound.Diphenylterazine alone yields very little background with excellent signal-to-background ratios. Furthermore, Diphenylterazine elicits minimal cell toxicity at millimolar concentrations. Diphenylterazine injections into untransfected BALB/c mice do not yield any background emission.
