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.

Application
- Rapid and zero-cost DNA extraction from soft-bodied insects for routine PCR-based applications.: This study used phosphate buffered saline (PBS) to develop a cost-effective and efficient method for DNA extraction from insects, facilitating routine PCR-based applications in molecular biology (Jangra & Ghosh, 2022).
- Injectable amnion hydrogel-mediated delivery of adipose-derived stem cells for osteoarthritis treatment.: PBS was utilized to prepare and deliver adipose-derived stem cells in an injectable hydrogel, showing potential for innovative osteoarthritis treatments (Bhattacharjee et al., 2022).
- Rapid and sensitive detection of SARS-CoV-2 infection using quantitative peptide enrichment LC-MS analysis.: This research employed PBS for sample preparation in a novel LC-MS method for detecting SARS-CoV-2, providing a rapid and sensitive diagnostic tool (Hober et al., 2021).

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
