Putrescine N-methyltransferase (PMT) catalyses S-adenosylmethionine (SAM) dependent methylation of the diamine putrescine. The product N-methylputrescine is the first specific metabolite on the route to nicotine, tropane, and nortropane alkaloids. PMT cDNA sequences were cloned from tobacco species and other Solanaceae

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

how accurate is the amount of 100mg putrescine 51799-100mg (analytical standard) Can I take the amount in vial unchecked for my standard solution (1mg/ml)? So I want to dissolve the entire content of the vial in 100ml.
1 回答-
For 100 milligrams, the amount per vial when packaged should be between 100-105 mg. Also, this product is somewhat volatile, so it is possible that some of it could evaporate over time. In short, this product is not provided as a quantitative standard; there is not necessarily exactly 100 milligrams per vial. But it is guaranteed to meet the specifications for appearance, purity and identity: https://www.sigmaaldrich.com/specification-sheets/370/087/51799-BULK.pdf
