Specificity: Fusion protein of a Fc fragment (human IgG1 isotype) and the extracellular domain of CTLA-4.
Purification method: This fusion protein was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
Background: Recombinant protein composed of the extracellular domain of CTLA-4 fused with the Fc region of human immunoglobulin gamma 1 (hIgG1). Abatacept binds to CD80 (B7-1) with more avidity than to CD86 (B7-2).
