WebAlthough streptavidin has been well characterized, the on-rate for biotin binding and the dissociation constant of the streptavidin-biotin complex commonly cited in the literature can be used as an approximation only. The dissociation constant was derived based on the on-rate of 7 × 10 7 m −1 s −1 and the off-rate of 2.8 × 10 −6 s −1 WebAffinity: "Affinity" simply refers to how strong the binding is (as judged by Kassociation or Kdissociation and ∆Go). "High affinity" refers to very strong binding (large negative …
Binding Affinity - an overview ScienceDirect Topics
Biotin and avidin bind with a dissociation constant of roughly 10 −15 M = 1 fM = 0.000001 nM. Ribonuclease inhibitor proteins may also bind to ribonuclease with a similar 10 −15 M affinity. The dissociation constant for a particular ligand-protein interaction can change significantly with solution conditions (e.g., … See more In chemistry, biochemistry, and pharmacology, a dissociation constant ($${\displaystyle K_{D}}$$) is a specific type of equilibrium constant that measures the propensity of a larger object to separate … See more For the deprotonation of acids, K is known as Ka, the acid dissociation constant.

WebThe dissociation constant, Kd, is equal to the ratio of the two rate constants for the binding reaction, koff /k on. Yet how the kinetics of NAb binding influences the potency and extent of neutralization is largely unexplored. It is known, though, that the higher the density of target cells and receptors, the greater the demands on neutralization.
