Physiology
A small molecule that, when combined with a larger carrier such as a protein, can elicit the production of antibodies that bind specifically to it (in the free or combined state).
Example sentences
  • It is likely that low-molecular-weight agents act as haptens, combining with human proteins in the respiratory tract to become complete immunogens.
  • Supporting this is the discovery by Vojdani et al., who reported that some individuals develop allergic antibodies to haptens formed in response to MTBE binding to albumin.
  • The bound microparticle complexes are then incubated with antidetection hapten alkaline phosphatase conjugate, which binds to the detection haptens.

Origin
