  • (18) Sometimes multivalency in the carbohydrate-receptor interaction is crucial.
  • (19) The distribution pattern of the clusters corresponded to that of absorbed and immunogold-labelled poliovirus particles and suggests a multivalent organization of poliovirus binding sites.
  • (20) This association is rapid, and, when triggered by multivalent antigen, it is quickly reversed by the addition of excess monovalent antigen.

Valency


Definition:

  • (n.) See Valence.
  • (n.) A unit of combining power; a so-called bond of affinity.

Example Sentences:

  • (1) The mixed-valence-state cytochrome oxidase mixed with O2 at -24 degrees C and flash-photolysed at -60 to -100 degrees C reacts with O2 and initially forms an oxy compound (A2) similar to that formed from the fully reduced state (A1).
  • (2) Additional results, together with simulations based on a simple kinetic model, suggest that the reduced apparent valence of the low slope component of the Q-V curve results from gating charge immobilization occurring at holding potential.
  • (3) A related explanation is that the 609 nm absorbance involves a charge-transfer interaction of both iron and copper as a mixed-valence binuclear complex, Cua3, having properties of a non-blue copper.
  • (4) RBDs were significantly more impaired than LBDs or NCs on category and valence accuracy, while LBDs posed expressions with significantly more intensity than RBDs or NCs.
  • (5) The extent of adsorption was affected by the concentration and valency of cations, indicating a charge-dependent process.
  • (6) Use of that principle was demonstrated by fourth grade children who judged that telling the truth, as opposed to lying, was shown by a consistency between the affective valence of the verbal and the nonverbal communications.
