Ranging from non-GMP grades for low-risk application, to IPEC-PQG GMP for higher-risk applications, we have products covering all your manufacturing needs.

Anwendung

DTT is an excellent reagent chemical used to reduce disulfide bonds commonly found in bioprocessing. DTT is used in buffer formulations to maintain and stabilize free -SH in applications such as protein based biotherapeutics and enzyme stability.

Ein hervorragendes Reagens, um SH-Gruppen in reduziertem Zustand zu halten; reduziert Disulfide quantitativ. DTT-Zugabe in den Probenpuffer ist ein effektives Mittel um Disulfidbindungen in Proteinen vor der Durchführung einer SDS-PAGE zu reduzieren. DTT kann auch dazu benutzt werden, um die Disulfid-Brücken des Crosslinkers N,N′-bis(acryloyl)cystamin zu spalten und dadurch die Matrix eines Polyacrylamidgels aufzulösen. DTT riecht weniger stechend und ist weniger giftig als 2-Mercaptoethanol. In der Regel genügt eine sieben Mal kleinere Konzentration an DTT (100 mM) als die, für 2-Mercaptoethanol notwendige (5% v/v, 700 mM).
