Primary VNAR Single Domain Antibodies

Explore primary VNAR single domain antibodies for specialist molecular and life science research. VNARs are compact antigen-binding domains derived from immunoglobulin new antigen receptors (IgNARs) found in cartilaginous fish, offering a structurally distinct alternative to camelid VHH antibodies.

About this antibody range

VNAR domains have a distinctive framework and binding-loop arrangement that differs from both conventional mammalian antibody variable domains and camelid VHHs. These characteristics have led to interest in VNAR technology for antigen recognition, protein engineering and the development of research binding reagents.

As with any antibody format, individual VNAR products should be selected on the basis of target recognition and experimentally supported performance. Consult the relevant datasheet for target, species reactivity, molecular characteristics, formulation and validated applications.

Key characteristics

  • Distinct single-domain antibody format derived from IgNAR biology
  • Compact antigen-recognition architecture
  • Of interest for molecular recognition and antibody engineering research
  • Suitability determined by individual product specifications and validation
