Abstract
An anti-mouse CXC chemokine receptor 6 (mCXCR6) monoclonal antibody (mAb), Cx6Mab-1, was developed recently. Cx6Mab-1 is applicable for flow cytometry, Western blotting, and enzyme-linked immunosorbent assay. The purpose of this study is to determine the binding epitope of Cx6Mab-1 using 2 × alanine mutated mCXCR6. Analysis of flow cytometry revealed that Cx6Mab-1 did not recognize S8A-A9G, L10A-Y11A, D12A-G13A, and H14A-Y15A mutants of mCXCR6. The results clearly indicate that the binding epitope of Cx6Mab-1 includes Ser8, Ala9, Leu10, Tyr11, Asp12, Gly13, His14, and Tyr15 of mCXCR6. The successful determination of the Cx6Mab-1 epitope might contribute to the pathophysiological investigation of mCXCR6.
