Transmembrane Protein VLPs

Transmembrane proteins are difficult to express in their natural 3D configuration. We use virus-like-particles (VLPs) derived from self-assembling viral capsid proteins to express transmembrane proteins in their natural conformation. VLPs are non-infectious and have high immunogenicity. Our line of VLP-displayed antigens can be used for antibody drug discovery of otherwise difficult targets.
