Western blot analysis of GST-Abl SH2 domain (Lane 1, 35kDa) (Product # 87702) and GST-Grb2 (Lane 2, 38kDa) SH2 domain (Product #87700) was performed by loading 2ug of each purified fusion protein onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with 5% BSA/0.1%TBST for at least 1 hour. Membranes were then probed with a mouse monoclonal antibody recognizing GST clone 8-826 (Product # MA4-004) at a dilution of 1:1000 overnight at 4°C on a rocking platform. Membranes were then washed in TBS/0.1%Tween-20 and probed with a goat anti-mouse-HRP secondary antibody (Product #31430) at a dilution of 1:25000 for at least one hour. Membranes were washed and chemiluminescent detection was performed using Pierce SuperSignal West Dura (Product #34075).

Epitope tags provide a method to localize gene products in a variety of cell types, study the topology of proteins and protein complexes, identify associated proteins, and characterize newly identified, low abundance or poorly immunogenic proteins when protein specific antibodies are not available. The GST (Glutathione-S-Transferase) is a 26kDa protein encoded by the parasite Schistosoma japonicum, easily purified by affinity chromatography on immobilized glutathione. GST is utilized as a fusion protein with foreign proteins in a range of prokaryotic expression vectors, including the pGEX family of vectors. Antibodies against GST will detect the expressed GST protein or a GST-fusion protein, and can be utilized for immuno-purification of GST-fusion proteins.
