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

Opis ogólny
Zastosowanie
- in the preparation of standard during the enzymatic measurement of plasma sphingomyelin levels[2]
- to study the binding of Vascular Anticoagulant α (VAC α) to planar phospholipid bilayers[3]
- to perform fluorescence polarization of PC16 (N-[α-N-palmitoyl-ε-N-(4-nitrobenz-2-oxa-1,3-diazole)-L-lysine]-2-aminoethanol-N- (trimethylaminoethanol) phosphate) in dispersions of co-sonicated lecithin and sphingomyelin[4]
- for reconstitution of viral ion channel protein M2 into liposomes[5]
- as a standard sample to define spectral fingerproint using Time-of-flight secondary ion mass spectrometry (ToF-SIMS)[6]
- to evaluate the contribution of various phospholipids to the formation of foam in the amniotic fluid[7]

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.
