◎Syphilis recombinant antigen production for Tp(Treponema pallidum) test
Transgenic silkworms efficiently produces recombinant syphilis antigen proteins Tp15-17 and Tp47, which are the raw materials for syphilis Tp test reagents for clinical diagnostic testing.
No need to use rabbits.

● Advantages of the above recombinant syphilis antigens
・Reasonable manufacturing costs
・High consistency among lots
・Low Non-specific background
・Low risk in animal welfare aspects
・Halal Certification materials
Since the antigen is expressed in the water-soluble protein of silk strings, it is easy to extract and its performance is comparable to that of natural products. The costs required for production (space, feed, management costs) are also much cheaper than other animals or organisms. The growth cycle is fast, so breeding is efficient and it does not take up much space, so production volume can be flexibly expanded. Since rabbits, which are mammals, are not used as production, it is advantageous in the future from the perspective of animal welfare.
