Phase 3 validated Tag/Catcher cVLP display platform

AdaptVac's iso-peptide display platform utilises our proprietary MoonCatcher/Tag pair.

​

Furthermore, the cVLP is based on Tag or Catcher fused Bacteriophage AP205 capsid protein, which spontaneously forms a capsid Virus-Like Particle during production in E.coli.

​

MoonCatcher and AP205 have now been through Phase 3 clinical testing in our ABNCoV2 COVID-19 vaccine program.

 

Demonstrating safety, scalability, as well as EU and US regulatory acceptance for our platform.
