Magenta-phos PT (Highly Pure) by Molecular Depot is a Magenta-phos PT, a white to off-white microcrystalline powder, a chromogenic alkaline phosphatase substrate that yields a magenta precipitate. Shifting the chlorine from position four to position six of the indole changes the colour of the indigo dimer from blue to magenta without changing how the substrate is cleaved. It is used to visualise alkaline phosphatase activity in histochemical and blot staining, in reporter gene assays and in double-labelling experiments. Each unit contains 250 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
