QVQ is a contract research organization offering services and reagents around single-domain antibodies (sdAbs, also called VHHs, or nanobodies).

SdAbs are fragments of heavy-chain-only antibodies found in camelids such as llamas. Their small size and uniquely shaped binding site make sdAbs highly stable and suitable for various targets and a wide range of research, diagnostic, and therapeutic applications.

QVQ is specialized in the discovery of tailor-made sdAbs. Our lead-discovery projects can be customized for affinity, epitope specificity, cross-species recognition, or functional activity. Although sdAbs are conventionally based on animals, QVQ is actively pursuing animal-free and computational approaches as well.
