ProtocolSDS

Application

  • For quantitative determination of alkaline phosphatase (ALP) activity using stable p-nitrophenol phosphate substrate.

Key Features

  • High sensitivity and wide linear range. Use 5 μL serum or plasma sample. The detection limit is 2 U/L, linear up to 800 U/L.
  • Homogeneous and simple procedure. Simple "mix-and-measure" procedure allows reliable quantitation of ALP activity within 5 minutes.
  • Robust and amenable to HTS. All reagents are compatible with high-throughput liquid handling instruments.

  • OD405nm

Samples

  • Serum, plasma etc

Species

  • All

Size

  • 250 tests

Detection Limit

  • 2 U/L

Shelf Life

  • 12 months

More Details

  • Alkaline phosphatase(ALP) catalyzes the hydrolysis of phosphate esters in an alkaline environment, resulting in the formation of an organic radical and inorganic phosphate. In mammals, this enzyme is found mainly in the liver and bones. Marked increase in serum ALP levels, a disease known as hyperalkalinephosphatasemia, has been associated with malignant biliary obstruction, primary biliary cirrhosis, primary sclerosing cholangitis, hepatic lymphoma and sarcoidosis. Simple, direct and automation-ready procedures for measuring ALP activity in serum are becoming popular in Research and Drug Discovery. BioAssay Systems QuantiChrom™ Alkaline Phosphatase Assay Kit is designed to measure ALP activity directly in biological samples without pretreatment. The improved method utilizes p-nitrophenyl phosphate that is hydrolyzed by ALP into a yellow colored product (maximal absorbance at 405nm). The rate of the reaction is directly proportional to the enzyme activity.

Can the calibrator and water blank be measured after the samples, and if so how long after?

We recommend measuring calibrator and water blank simultaneously with the samples, to avoid any potential sources of error, but it is not essential. Potential sources of error that can be introduced by non-simultaneous measurement are: variations in pipetting volumes, variation in microplate reader performance, evaporation of reagents caused by long incubation, etc.

There are yellow chrystals in the pNPP vial - can I still use the product?

Yes, but you first have to dissolve the crystals. The yellow crystals are phenol which has separated from the reagent during the freezing process. Heat the vial until all phenol crystals disappear (melting point is around 40 °C), and mix well before use.

Is pNPP light sensitive? Does it need to be handled in the dark room only, and dark colored 96well plates necessary?

pNPP is light sensitive and must be stored protected from light, but it can be used under normal laboratory conditions. Only clear flat bottom microplates should be used. Do not use plates, where the bottom is not clear and flat.

How do I measure ALP activity animal tissue?

Homogenize tissue sample in 10 mM Tris Buffer (pH 8.5), 50 mM NaCl, or lysis buffer of your choice.- The assay is compatible with up to 2% SDS or Tween-20 in the sample.- The assay is incompatible with EDTA, oxalate, fluoride, citrate.- Centrifuge homogenized tissue sample at 10,000 x g for 10 min at 4°C.- Use the clear supernatant for alkaline phosphatase assay.For more detailed product information and questions, please feel free to Contact Us.
