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.

General description
Instaura interazioni specifiche con i residui di cisteina e di istidina delle proteine, interferendo perciò con enzimi come la ribonucleasi. Se anche la sua reazione con l′istidina è lenta, le sue proprietà inibitorie forniscono un prezioso contributo alla ricerca sulle proteasi, come le cisteina proteasi. La iodoacetammide è nota per la sua azione inibitoria irreversibile nei confronti degli enzimi e la sua efficacia nel dare luogo a derivati stabili delle proteine, proprietà che la rendono preziosa nello studio delle strutture e del comportamento delle proteine e dell′inibizione degli enzimi.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 risposta-
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's the solubility in pure ethanol? Do you offer smaller aliquots?
1 risposta-
This product is currently only offered in the 56 mg pack size. The solubility is tested in acetone at 50 mg/mL and it is also listed as being soluble in water at 50 mg/mL. According to a literature review, it should also be soluble in ethanol, but a concentration is not stated so experimentation will be necessary to determine the optimal solubility parameters.
