pGEX vectors are frequently utilized in bacterial systems to express polypeptides or entire proteins as fusions with glutathione S-transferase.
Using this fusion system, a polypeptide sequence is linked to the C-terminus of the 26 kD GST protein from Schistosoma japonicum.
The bacterially expressed GST-fusion proteins are purified by absorption with glutathione-agarose beads.
The fusion protein is subsequently eluted from the glutathione agarose with an excess of free glutathione.
Antibodies to GST are used to detect pGEX-expressed fusion proteins and as immuno-affinity reagents for purification of recombinant proteins.
Applications:Suitable for use in ELISA and Western Blot.
Other applications not tested.
Recommended Dilution:ELISA (solid phase = antigen): 0.1-1.0ug/mlELISA (solid phase = antibody): 1.0ug/mlWestern Blotting: 1ug/mlOptimal dilution determined by the researcher.
