Anwendung
1-Thioglycerin ist ein Derivatisierungsmittel und wurde zur Untersuchung der pH-abhängigen Photolumineszenz von wässrigen CdTe-Nanokristallen mit Thiol-Endgruppen verwendet. 1-Thioglycerol wird zur Entwicklung und zum Testen von Thiol-funktionalisierten Copolymeren eingesetzt. 1-Thioglycerol wird auch als Post-Modifikations-Substanz bei der Erzeugung von atypischen Peptid-Foldameren verwendet.Potenzieller Ersatz für 2-Mercaptoethanol; Sonde zur Untersuchung von Lymphozytenaktivierung[1].
Angaben zur Herstellung
Dieses Produkt ist mit Ethanol mischbar (1 ml/mL, 50 %, v/v) und erzeugt eine klare, farblose Lösung. Es ist auch mit Wasser mischbar (0,1 M).

Biomaterial-mediated complement activation repeatedly has been invoked as a trigger of phagocyte reactions and inflammation. However, a direct correlation between complement activation and inflammatory responses to biomaterial surfaces has yet to be established. Using an animal implantation model and gold

Cloretazine (VNP40101M; 101M; 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)-2-[(methylamino)carbonyl]hydrazine) is a sulfonylhydrazine prodrug that generates both chloroethylating and carbamoylating species on activation. To explore the molecular mechanisms underlying the broad anticancer activity observed in preclinical studies, cloretazine and chloroethylating-only [i.e., 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)hydrazine] and carbamoylating-only (i.e., 1,2-bis(methylsulfonyl)-1-[(methylamino)carbonyl]hydrazine)

Tissue inhibitors of metalloproteinases (TIMPs) regulate matrix metalloproteinase activity and maintain extracellular matrix homeostasis. Although TIMP-3 has multiple functions (e.g., apoptosis, inhibition of VEGF binding to VEGF receptor, and inhibition of TNFα converting enzyme), its roles in thermogenesis and metabolism

What is the concentration of the 1-thioglycerol?
1 answer-
The liquid is not a solution of 1-thioglycerol in some solvent. Rather, it is a neat liquid (i.e., essentially pure 1-thioglycerol). Based on a density of 1.245 g/mL and a molecular weight of 108.2 g/mole, one can calculate an effective molarity of 11.5 M. This information may be found on the M1753 product information sheet.

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
