    Human LTA amino acid Leu35-Leu205, with an N-terminal linker, a TEV (tobacco etch virus)+linker, and an N-terminal human 6xHis-tag, was expressed in mammalian cells. The resulting product is the recombinant human LTA antigen. The purity of this LTA protein reaches up to 95% detected by SDS-PAGE. This protein ran at a molecular weight of about 21 kDa by SDS-PAGE due to glycosylation. Its endotoxin content is less than 1.0 EU/ug determined by the LAL method. The bioactivity of this recombinant LTA protein was measured in the functional ELISA. This LTA protein can bind to the human TNFRSF1B or human TNFR1, with the EC50 constant of 1.632-2.699 ng/ml and 4.409-6.797 ng/ml, respectively. And it is available now.

    LTA, the closest homolog to TNFα, has specific roles in the development and function of the immune system, mainly in lymphoid organ development, organization and maintenance of lymphoid microenvironments, host defense, and inflammation.
