Aplicación
Staphylococcal enterotoxin B (SEB) which binds to MHC class II molecules and specific Vβ regions of T cell receptors (TCR), resulting in the activation of both monocytes/macrophages and T lymphocytes may be used as a superantigen and immune system activator. SEB may be used as a reference material in the development of SEB detection systems.

Prevalent incidents support the notion that toxins, produced by bacteria, fungi, plants or animals are increasingly responsible for food poisoning or intoxication. Owing to their high toxicity some toxins are also regarded as potential biological warfare agents. Accordingly, control, detection

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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

こんにちは、この商品の容量をお聞きしたいのですが、1MGと表記されている場合、1miligramということでしょうか？ 溶かしてから調剤したいのですが。 溶かして調剤する際のプロトコルはあるのでしょうか？
1 answer-
Yes, the 1MG does stand for one milligram. The product is soluble in water at 4 mg/ml. It may also be dissolved in an aqueous buffer such as PBS. See the link below to the product information sheet for additional solution stability information:
