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

What is recommended for the storage of longer duration once opened? Is it better to keep at 2°C-8°C for 1-2 years or to freeze it (-80°C or -20°C) and thaw it gently when needed?
1 回答-
This product is stable at 2-8°C at least until the assigned retest date, provided that no contaminants have been introduced. The recommended retest date is lot specific and reported in the product Certificate of Analysis. The stability of the product in dilute form or beyond the assigned retest date has not been determined. However, LPS products prepared from the powder form may be stored in 1 mg/mL aliquots for up to 2 years at -20°C. The storage of solutions at -80°C has not been determined. Please see the link below to review additional information regarding the stability and preparation of Lipopolysaccharides:
