Immobilized Biotinylated Human HLA-A*02:01&B2M&Foxp3 (TLIRWAILEA) Monomer, His-Avi tag at 1μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Anti-B2M Antibody, mFc Tag with the EC50 of 19.7ng/ml determined by ELISA.
Background
TLIRWAILEA is position 344-353 of Foxp3 which is a member of a large forkhead family of related proteins. The peptide has minimal homology with other Foxp family members, such as Foxp1, 2 and 4, and it has also been shown to induce strong peptide-specific CD8+ T cell responses, which recognize Foxp3+/HLA-A*02:01+ cutaneous T lymphoma cells.
