Virus-Like Particles

Virus-like particles (VLPs) comprise the structural proteins of a viral particle, but don’t contain genomic material, making them non-infectious, while presenting all of the structural epitopes of a native virus. Because of these properties, VLPs have been extensively used in diagnostic and vaccine R&D over recent years. The Native Antigen Company offers a range of over 20 virus-like particles, produced from our proprietary VirtuE™ (HEK293) and insect-baculovirus expression systems.
