General description

Creatinine is generated from creatine by nonenzymatic dehydration. Creatinine is produced at a constant rate and is excreted from the body through kidney glomerular filtration. Decreased kidney function can effect the rate at which creatinine is filtered by the kidneys and can be used as a measure of kidney function. Decreased kidney function can result in increased serum creatinine levels due to the inability to clear creatinine through urine excretion. Creatinine levels can be affected by changes in muscle mass, pregnancy, or the use of angiotensin inhibitors or angiotensin receptor antagonists.

Application

Creatinine Assay Kit has been used to measure the creatinine concentration in samples.[1][2]
Suitable for use with cell and tissue culture supernatants as well as serum, plasma, urine, and other biological fluids.

Biochem/physiol Actions

In this assay, Creatinine concentration is determined by a coupled enzyme reaction, which results in a colorimetric (570 nm)/fluorometric (λex = 535em/λ = 587 nm) product, proportional to the creatinine present.

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. What is the sensitivity and limit of detection for both the colorimetric and fluorometric?

    1 answer

    1. Sensitivity limits are based on instructions for preparation of the kit's standard curves. The colorimetric range is 0 to 10 nmole of creatinine per well, and the fluorometric range is 0 to 1.0 nmole of creatinine per well. Please note that this product has been discontinued and is no longer supported.

  3. 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
