Malachite Green Phosphate Assay Kit

What is the difference between your 3 phosphate assays: DIPI-500, POMG-25H, POPB-500?

All three products are based on the malachite green dye. While the PiBlue (POPB-500) and QuantiChrom (DIPI-500) Phosphate Assay Reagents are identical, they differ in the standards. The PiBlue is designed for customers who want prepare a full calibration curve for their assays, and the latter has one set of a blank control and 30 µM phosphate standard. The reagent is more diluted than the reagent used in the Malachite Green Phosphate Assay Kit (POMG-25H). As a result, one adds 100 µL reagent (POPB-500 or DIPI-500) to 50 µL sample, whereas for the Malachite Green based assay, one adds 20 µL Reagent to 80 µL sample. In practice, the DIPI-500 is the most convenient kit to use, because there is no need to prepare a calibration curve there is no need for extra mixing. Because adding a larger volume (100 μL) to a small volume (50 μL) effects efficient mixing in well, no extra mixing is needed. The POPB-500 requires preparation of calibration curve. With the POMG-25H Kit, one needs to mix the reagent with the sample, because adding 20 µL to 80 µL does not mix efficiently by itself. Also a preparation of a standard curve is necessary.For more detailed product information and questions, please feel free to Contact Us.
