Treponema Pallidum (TP) Recombinant Antigen
Treponema pallidum is the causative agent of syphilis, a sexually transmitted disease (STD). A blood test for syphilis antibodies is an important way to determine whether someone has syphilis. We have screened out the immuno-dominant epitope genes of TP coming from TP15, TP17, TP47 and expressed each epitope gene as well as multiple-epitope genes to get recombinant antigens with good activity and high specificity. The recombinant antigens can be easily conjugated with HRP. They can be used in double antigen sandwich ELISA kits and rapid test kits.

Beijing Hotgen Biotech Co.,Ltd, which is located in Beijing Zhongguancun High-tech
development zone, is a high-tech enterprise. We offer IVD raw materials, diagnostic
reagents, and OEM service as well.
Hotgen Biotech is one of the main suppliers of IVD biological raw materials in China. The
raw materials, including recombinant antigens and monoclonal antibodies, have been
exported to North America. Our products are popular due to high quality, and little
variation between each batch.
