Western Blotting (1 paper)

N-terminally expressed GST-tagged proteins were over expressed and purified from E. coli. Purified proteins were analyzed by western blot using HRP-conjugated rabbit anti-GST antibody at a concentration of 20ng/ml.

Rabbit Anti-Glutathione-S-Transferase (GST)-Peroxidase Conjugate antibody has been used for western blot analaysis at a dilution of 1:500. The antibody can also be used for direct ELISA at 1:10,000.

General description

Recombinant target proteins are often expressed as a fusion product with Glutathione-S-Transferase (GST) tags using various expression vector constructs. Thus, antibodies directed against the GST tags of the recombinant constructs can facilitate the purification and study of target proteins.

The antibody is specific for native as well as denatured-reduced forms of glutathione-S-transferase from Schistosoma japonicum. Anti-GST may be used in various immunoassays to identify the expression of GST fusion proteins.
