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.

Description générale
Application
- pour sélectionner le phénotype de résistance à l'ampicilline dans les cellules transformées et comportant des mutations.
Actions biochimiques/physiologiques
Mode de résistance : les bêta-lactamases clivent le cycle bêta-lactame de l'ampicilline, la rendant inactive.
Spectre antimicrobien : agit sur les bactéries à Gram positif (activité comparable à la benzylpénicilline) et à Gram négatif (activité comparable aux tétracyclines et au chloramphénicol).
Caractéristiques et avantages
- Antibiotique de grande qualité convenant à de nombreuses applications de recherche.
- Idéal pour la recherche en biochimie et en biologie cellulaire.

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