Camelid VHH Antibody (also called single-domain antibody, sdAb or Nanobody by Ablynx) is a peptide chain about 110 amino acids in length, containing one variable domain of a heavy-chain antibody (a VHH fragment). Like a whole antibody, the camelid VHH antibody is able to bind selectively to a specific antigen. This single-domain antibody has a broad range of applications in biotechnical and therapeutic research fields due to its small size, simple production and high affinity. GenScript’s MonoRab™ Anti-Camelid VHH Affinity Resin (Cat. No. L00905) is designed for purification of Camelid VHH single domain antibody from commonly used protein expression systems such as bacteria, yeast and mammalian cells. The VHH single domain antibody in cell lysate can specifically bind to the Anti-Camelid VHH monoclonal antibody coupled to the resin. Nonspecific binding reactions are eliminated by stringent washing steps, and the purified target protein is eluted with a high recovery rate. Table 1 lists the main characteristics of GenScript’s MonoRab™ Anti-Camelid VHH Affinity Resin.
