Beryllon II is a widely used chromogenic reagent that has been used to determine many elements, such as Mo, Mg and Co. Beryllon II-Al³⁺complex with the addition of protein can potently enhance the Rayleigh light scattering, and used to determine proteins^[1] .

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
