The V5 epitope tag is derived from a small epitope(Pk) present on the P and V proteins of theparamyxovirus of simian virus 5 (SV5). The V5 tag isusually used with all 14 amino acids (GKPIPNPLLGLDST), and useful for western blotting,immunofluorescence and immunoprecipitation experiments.

GST (Glutathione S-Transferase) is a 26kDa protein，encoded by the parasitic helminth Schistosoma japonicum and widely used in the pGEX family of GSTplasmid expression vectors as a fusion protein with foreign proteins.This antibody can recognize both
