Recombinant expression of potentially immunosupressive proteins of the tick vector amblyomma variegatum. por Wang'ombe, G.N.

“…Recombinant proteins were expressed using E. coli and purified as insoluble inclusion bodies using immobilized metal affinity chromatography (IMAC). SDS-PAGE and western blot analyses shows that these tick proteins are stable when expressed and purified from E. coli, despite theirinsolubility.The function and usefulness of these insoluble proteins as protective antigens incattle remains to be determined. …”
