Rhodamine B base
Rhodamine B base, Dye content 97% (Solvent Red 49).
Rhodamine B base is a colourless dye with undetectable fluorescence feature. In acidic condition, rhodamine B base gets transformed into a colored rhodamine dye that acts as a stable and efficient laser dye. Rhodamine B base has been used as a marker in the experiment to determine the mating of B. thuringiensis-resistant females with B. thuringiensis-resistant and B. thuringiensis-susceptible males in reciprocal orders.
