Opis ogólny

The Free Glycerol Reagent provides a precise method for measuring free endogenous glycerol levels through coupled enzyme reactions, bypassing the need for initial lipase hydrolysis. Unlike triglycerides, which are typically bound to proteins and transported in plasma, free glycerol circulates independently. The innovative approach involves enzymatic or alkaline hydrolysis of triglycerides, liberating glycerol and free fatty acids for accurate measurement.

The Serum Triglyceride Determination Kit (Catalog Number TR0100) offers a comprehensive solution for assessing glycerol, true triglycerides, or total triglycerides in serum or plasma samples. Utilizing lipase enzymatic hydrolysis, triglycerides are converted into glycerol and free fatty acids, enabling precise quantification through coupled enzyme reactions by F6428.

Unlike many commercially available triglyceride reagents, this method distinguishes between endogenous glycerol and glycerol derived from lipase hydrolysis of glycerides. With this advanced technology, researchers can confidently analyze glycerol levels with exceptional accuracy and reliability.

Zastosowanie

The Free Glycerol Reagent facilitates the quantitative enzymatic determination of glycerol levels in serum or plasma. Additionally, it may also be used to measure glycerol release from lipolysis in adipose tissue.[1][2]

Działania biochem./fizjol.

Glycerol undergoes phosphorylation through the enzymatic action of glycerol kinase (GK), utilizing adenosine-5′-triphosphate (ATP) to produce glycerol-1-phosphate (G-1-P) and adenosine-5′-diphosphate (ADP). Subsequently, glycerol-1-phosphate (G-1-P) is oxidized by glycerol phosphate oxidase (GPO) to yield dihydroxyacetone phosphate (DAP) and hydrogen peroxide (H2O2). This process involves peroxidase (POD), which catalyzes the coupling of hydrogen peroxide (H2O2) with 4-aminoantipyrine (4-AAP) and sodium N-ethyl-N-(3-sulfopropyl) m-anisidine (ESPA) to generate a quinoneimine dye exhibiting an absorbance maximum at 540 nm.The observed increase in absorbance at 540 nm correlates directly with the concentration of free glycerol present in the sample. This method provides a reliable means for quantifying free glycerol levels, enabling accurate assessment of biochemical samples.

Cechy i korzyści

  • Simplified Process: Streamline your workflow with a single reagent, offering a quick 5-minute reaction time.
  • User-Friendly Design: Eliminate the need for weighing or mixing multiple reagents, ensuring ease of use and efficiency.

Zasada

The free glycerol reagent uses coupled enzyme reactions resulting in an increase in absorbance at 540 nm that is directly proportional to the glycerol concentration.

Powiązanie

In addition to kits, the individual reagents and glycerol standard are available separately when fewer reactions are needed.

Questions

1–3 of 3 Questions  
  1. 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

  2. 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.
