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.

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

Can LPS bind to plastics (ex. 1.5 mL microtube) even when LPS solution is frozen stored at -20℃? I store LPS solution at 0.05mg/mL in -20℃ now.
1 回答-
LSP is less likely to stick to plastics than glass, however very low concentrations (<0.1 mg/mL in water), LPS tends to stick to containers made
of certain types of glass or plastic. To minimize, prepare stock solutions of at least 1 mg/mL. If the LPS concentration is >1 mg/mL, adsorption to the sides of the vial is
negligible. For solutions stored in glass, vortexing for 30 minutes following thaw is recommended to redissolve. This may be useful for dilute solutions in plastic, as well. Surfaces (glass and plastics) may be salinized to reduce adherence.See Sigmacote, SL2:
