(57) [Summary] [Structure] A Treponema pallidum fusion antigen in which a plurality of Treponema pallidum antigens are fused, and a method for measuring anti- Treponema pallidum antibody using the fusion antigen. [Effect] According to the present invention, a Tp fusion antigen having high reactivity with an anti-Tp antibody can be obtained by a simple purification operation, and by using the fusion antigen in an anti-Tp antibody measurement method, the anti-Tp antibody can be obtained with higher sensitivity than before. Can be measured. |
