  • Process for preparing purified syphilis antigen from Treponema palljdum
    Patent number: 5474900
    Abstract: A process for preparing a purified syphilis antigen from Treponema pallidum is presented. The process comprises the steps of obtaining an extract from Treponema pallidum, adsorbing the extract onto hydroxyapatite gel and eluting the antigen in the presence of a surfactant. The preferred surfactant is octylglucopyranoside, A diagnostic agent is prepared which comprises the purified syphilis antigen adsorbed on an inert carrier, which carrier at least partially a hydrophobic carrier to which the antigen is adsorbed.
