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 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

What method was used to extract LTA?
1 answer-
The specific methodology for the manufacturing process of this product is proprietary. Lipoteichoic acid is a polymer derived from bacterial cell walls, meaning it is isolated from these structures. One common method discussed in literature for extracting lipoteichoic acid involves cell lysis followed by hot phenol/water extraction.

How is it bettere to resuspend the powder? Please add solubility and how to use the product in the "fiche des caractéristique"
1 answer-
As mentioned in the Product Datasheet, Lipoteichoic acid is soluble in water (5 mg/ml), yielding
a hazy colorless to faint yellow solution. This document can be located in the 'DOCUMENTATION' section under 'More Documents':
