This reagent has not been specifically tested for use with media samples. However, freezing at -20°C or -80°C prior to analysis is expected to be acceptable. As a general practice, avoid multiple freeze–thaw cycles. Thaw samples slowly, either in a refrigerator overnight or at ambient temperature. Mix samples well by gently inverting several times prior to testing. Samples should be analyzed within 24–48 hours. While glycerol in solution is quite stable, the frozen storage time for samples has not been determined.

General description
Das Kit zur Bestimmung von Serumtriglycerid (Katalognummer TR0100) stellt eine umfassende Lösung zur Messung von Glycerin, echten Triglyceriden oder Gesamttriglyzeriden in Serum- oder Plasmaproben dar. Mittels enzymatischer Hydrolyse durch eine Lipase werden Triglyceride zu Glycerin und freie Fettsäuren aufgespaltet, was eine präzise Quantifizierung durch gekoppelte Enzymreaktionen durch F6428 ermöglicht.
Im Gegensatz zu vielen handelsüblichen Triglycerid-Reagenzien unterscheidet diese Methode zwischen endogenem Glycerin und Glycerin, das aus der Lipase-Hydrolyse von Glyceriden hervorgegangen ist. Mit dieser fortschrittlichen Technologie lässt sich der Glyceringehalt zuverlässig und mit außergewöhnlicher Genauigkeit analysieren.

Can the KRBH medium collected for glycerol measurement with F6428 be stored at −80°C before the assay, or should it be analyzed fresh? If freezing is acceptable, what storage time do you recommend?

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

I would like to measure the concentration of free glycerol in the culture supernatant of adipocytes using this reagent with a plate reader instead of a cuvette. What are recommended sample and reagent volumes for a plate reader? Have you ever tested?
1 answer-
This product has not been tested for use with a well plate format. The product instructions call for a total volume of 830 µL, where 10 µL each of water, glycerol standard, and sample are added to cuvettes containing 800 µL of Free Glycerol Reagent. Most 96-well plates have a working volume of 100-300 µL, so the volume of each component would need to be scaled accordingly. Adding 3 µL each of water, glycerol standard, and sample to wells containing 240 µL of Free Glycerol Reagent would result in the same concentrations with a total volume of 249 µL. Regardless, the functionality of a plate reader in this application cannot be guaranteed and would need to be assessed independently.

I have an old version of this product (6428) - just one bottle not a kit. I need to reconstitute this but can't find instructions. Can you let me know what to reconstitute in and how much? Thank you!
1 answer-
There are no specific instructions for 6428. F6428 is one bottle of reagent as well. The user guide of F6428 may serve as a reference. A typical reconstitution procedure of F6428 is: Reconstitute the Free Glycerol Reagent with 40 ml of water. After addition of water, stopper the vials, and immediately mix several times by inversion. DO NOT SHAKE. Protect the reagent from light by storing in amber bottles. Please check page 2 of the user guide here:

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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

Could you kindly send me a package insert and a manual application for determination on automated clinical systems? Many thanks.
1 answer-
The Free Glycerol Reagent is for R&D use only, not for in vitro diagnostic use, drug, household, or other uses. Please consult the Material Safety Data Sheet for information regarding hazards and safe handling practices.
