Advantages of VHHS

Advantages of VHHS

Structural Advantages:​​

  • The CDR3 loop of a camelid VHH typically can be much longer allowing it to reach epitopes on target antigens inaccessible to conventional antibodies.​​
  • VHH is its entirely hydrophilic framework, whereas a VH domain contains a hydrophobic side facing the VL domain (indicated in black)​. This may aid inclusion of vHHs into bi-specific antibodies and alternative formats. ​

Therapeutic Advantages:​​

  • Their nanoscale dimensions enable deep penetration of tumors (15kDa, Diameter: 2.5nm)​​
  • Certain nanobodies able to cross the blood brain barrier (BBB)​​
  • High affinity and specificity for their target antigens​​
  • Modularity, can be used as soluble fragment or fused t...Read more

  • Certain nanobodies able to cross the blood brain barrier (BBB)​​
  • High affinity and specificity for their target antigens​​
  • Modularity, can be used as soluble fragment or fused to FC or HSA or CAR-T receptors in bi- or multi-specific formats​​

​​Developability Advantages:​​

  • High melting temperatures (60–80◦C, several weeks at 37◦C)​​
  • Non-physiological pHs (3.0–9.0)​​
  • Strong chemical denaturants (2–3 M guanidinium chloride, 6–8 M urea)​​

​​Manufacturing Advantages:​​

  • Nanobodies are inexpensive to produce​ and can leverage existing manufacturing processes.​
  • Leverage standard Protein-A purification.​
  • Can be synthesized through microbial or mammalian expression systems​​
