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.
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%).
Freeze at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
