[Separation and purification of Treponema pallidum by density gradient. Technical note].
The reported possibility of obtaining purified suspension of Treponema pallidum through a Percoll density gradient is evaluated. The maintenance of motility and antigenicity of the purified T. pallidum allows further studies on antigenic structure of treponemes.
