General description

L(+)-Lactate is a metabolic compound formed in animals by the action of the enzyme Lactate Dehydrogenase. Lactate is produced in proliferating cells and during anaerobic conditions such as exercise. Abnormally high concentrations of lactate have been related to pathological conditions such as cancer, diabetes, and lactate acidosis. L(+)-Lactate is the major stereoisomer of lactate formed in human intermediary metabolism and is present in blood at levels of around 1-2 mmol/L. This kit provides a convenient means for detecting L(+)-Lactate in biological samples. There is no need of pretreatment or purification of samples.

Application

Lactate Assay Kit has been used to determine the concentrations of lactate in samples.
Suitable for detecting L(+)-Lactate in culture medium, fermentation medium, blood and cells.

Biochem/physiol Actions

In this assay, lactate concentration is determined by an enzymatic assay, which results in a colorimetric (570 nm)/ fluorometric (λex = 535 nm/λem = 587 nm) product, proportional to the lactate present. Typical levels of sensitivity for this kit are between 0.001-10 mM.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Can I make up my own Lactate standard to use with Product MAK064, Lactate Assay kit?

    Unfortunately, no. If you run the 100 mM L-(+)-Lactate standard (MAK064D) that comes with the kit, you should get good results. However, if you just use, for example, a solution of sodium L-(+)-lactate dissolved in water or buffer, you probably won't get good results. There are cofactors present in biological samples and in the L-(+)-Lactate standard that comes with the kit (which is not a pure solution of sodium L-(+)-Lactate in water or buffer). If such a "homemade" standard solution were to be spiked with a biological sample or the kit standard, the calculations would be more complicated, but the assay should work.
