Expression and purification of L. infantum recombinant proteins. The images show Coomassie blue-stained sodium dodecyl sulfate-4 to 20% polyacrylamide gradient gels containing uninduced E. coli lysates (lanes 1), induced lysates (lanes 2), and purified proteins (lanes 3). Sizes are shown in kDa. The apparent molecular masses of the proteins were comparable to their predicted molecular masses.
