Single Domain Antibody Discovery

Alpaca heavy chain antibody (HcAb) is a naturally occurring special antibody composed of only two heavy chains, each has one heavy chain variable domain (VHH in Antibody) and two conventional CH2 and CH3 domains . Alpaca heavy chain antibodies specifically bind to antigens through a variable domain (VHH) on the heavy chain, which can exist stably in vitro alone. The molecular weight of VHH is only 1/10 (about 15KD) of the conventional antibody, but it has complete antigen recognition ability.
  • High Stability，Mass Industrial Production
  • Higher Tissue Penetration
  • High Specificity
  • Suitable for Modification
  • Low Immunogenicity, Easy Humanization

Anti-Tag VHH Beads

Anti-Tag VHH beads are based on agarose beads or magnetic beads which are covalently coupled with alpaca VHHs with excellent performance and can pull down specific tag-fused protein and its interaction factors from tissues.
