General description

Our SAFC Pharma^® portfolio of high-quality products for biopharmaceutical processing withstands strict quality control procedures and is produced according to MQ-500 requirements as defined by the M-Clarity program.
M-Clarity Program
As part of our Emprove^® Program, our raw materials are offered with Emprove^® Dossiers which provide comprehensive, up-to-date documentation to help you navigate regulatory challenges, manage risks, and improve your manufacturing processes.
Our comprehensive portfolio of downstream process chemicals not only provides biopharmaceutical manufacturers with high-quality raw materials for production of classical and novel therapies, but also helps them get to market faster and simplify regulatory challenges. 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.

Application

Un reactivo excelente para el mantenimiento de los grupos SH en estado reducido; reduce cuantitativamente los disulfuros. El DTT reduce de manera eficaz los enlaces disulfuro de las proteínas en tampones de muestra antes de la SDS-PAGE. El DTT puede utilizarse también para reducir el puente disulfuro del reticulante N,N′-bis(acriloil)cistamina con el fin de separar la matriz de un gel de poliacrilamida. El DTT es menos mordaz y menos tóxico que el 2-mercaptoetanol. Normalmente se requiere una concentración de DTT siete veces inferior (100 mM) a la concentración utilizada del 2-mercaptoetanol (5 % v/v, 700 mM).

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.
