Expression and purification of MaMIF. (A) SDS-PAGE analysis of purified MaMIF suggesting an approximate molecular mass of ~12.5 kDa for the monomer. (B) Superdex 75 10/300 GL analytical size-exclusion chromatography profile of MaMIF suggesting an apparent molecular mass of ~39 kDa in solution, corresponding to the size of a trimeric form. (C) CD spectrum of MaMIF confirming a properly folded protein. The pie chart in the inset shows the secondary structure make-up of the protein. (D) Western blot analysis with polyclonal anti-His and anti-MIF antibodies confirming the expressed protein to be MaMIF. (E) Western blot analysis with isotype-matched primary antibody shows the background level of antibody binding to the protein.
