General description

Phosphate is an essential component in living organisms and contributes to a variety of biological functions, including structural roles within nucleic acids, cellular membranes, and bone. Phosphate is also important in the transport of cellular energy, nucleic acid metabolism, and signal transduction. Hyperphosphatemia, a condition of excess phosphate levels in the blood, can lead to calcification of organs and interference with usage of other inorganic ions, such as iron, calcium, magnesium, and zinc.

The Phosphate Colorimetric Assay Kit provides a simple and direct procedure for measuring phosphate in a variety of samples. Phosphate reacts with a chromogenic complex, which results in a colorimetric (650 nm) product proportional to the amount of phosphate present. Phosphate concentrations between 1 μM and 1 mM, with a lower limit of detection of 0.1 nmol, can be directly determined.

Application

Phosphate colorimetric kit has been used to measure the phosphate concentration in a variety of samples.[1][2][3]

Suitability

Suitable for measuring phosphate levels in a variety of samples including serum and urine

Principle

The Phosphate Colorimetric Assay Kit provides a simple and direct procedure for measuring phosphate in a variety of samples. Phosphate reacts with a chromogenic complex, which results in a colorimetric (650 nm) product proportional to the amount of phosphate present. Phosphate concentrations between 1 μM and 1 mM, with a lower limit of detection of 0.1 nmol, can be directly determined.

Questions

1–3 of 3 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
