Description

General description

Our SAFC^® 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

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.

An excellent reagent for maintaining SH groups in reduced state; quantitatively reduces disulfides. DTT is effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N′-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol. Typically, a seven fold lower concentration of DTT (100 mM) is needed than is used for 2-mercaptoethanol (5% v/v, 700 mM).
