General description

Free fatty acids, also know as nonesterified fatty acids, circulate in the plasma bound to albumin. The majority of free fatty acids are derived from either dietary sources or are mobilized from adipose tissue. Plasma free fatty acids are elevated in many obesity-related disorders and may contribute to insulin resistance in peripheral tissues. Conditions such as sepsis and tumors producing lipoactive homones may also be associated with elevated free fatty acid levels.

Abnormalities in fatty acid metabolism causes fatty liver disease. Accumulation of free fatty acid in myocytes leads to the risk of cardiac dysfunction. Increased fatty acid β-oxidation is implicated in cardiac ischemia.

Application

Free Fatty Acid Quantitation Kit has been used in the following:
  • to measure lipid hydrolysis, by determining the free fatty acid in digested sample.
  • to measure plasma and serum free fatty acids level.
  • to quantify free fatty acids level in liver tissue.

Suitability

Suitable for detecting the long-chain free fatty acids in various biological samples, such as serum, plasma and other body fluids, food, growth media, etc.

Principle

In this kit, the concentration of fatty acids (C8 and longer) is determined by a coupled enzyme assay, which results in a colorimetric (570 nm)/ fluorometric (λex = 535/λem = 587 nm) product, proportional to the fatty acids present.

  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 these kits be used with serum samples from mouse?

    Yes, this kit can be used on mouse serum samples. We generally recommend that fresh serum samples be used. Frozen samples can probably be used. However, the successful use of frozen samples depends on the efficiency of freezing them and the amount of time they have been frozen. If previously frozen serum samples are used, you may want to check the performance of the kit with fresh vs. frozen samples.
