Quality Native Syphilis (Treponemal) Raw Material

White Antibodies is one of the largest bulk manufacturers of Treponema pallidum antigen used for the diagnosis of syphilis

Our Treponemes were originally sourced from leading GUM clinics in London in the 1970’s however it is possible that the bug has changed over time, to this end we replenish our seed stock to ensure we have the most current sub strains infecting the population.

We hold several cell lines of the Nichols strain of T.pallidum in secure offsite Liquid Nitrogen stores for use to seed production batches.

With over 30 years of experience refining production processes we have developed two key purity grades of antigen.

  1. Grade One – a cleaner harvest using refined processes.
  2. Grade Two – A superior antigen for use in TPHA manufacture containing background (ballast) cells of immune response which protects the treponemes during signification during kit manufacture.

Improved Sensitivity & Specificity
