WebApr 14, 2024 · At the end of dissociation, the anti-resistin surfaces were regenerated with a 30 s pulse of 10 mM glycine pH 1.5 at 30 uL/min. Sensorgrams were double referenced to the blank anti-resistin sensor surface and analyzed for binding affinity and kinetics using the 1:1 binding model in the Biacore T200 Evaluation software (v3.0.2). 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. WebExplain the different shape of the binding curves. Both proteins show cooperative ligand binding: A shows positive cooperativity (nH > 1) while B has negative cooperativity (nH < 1). This determines the shape of the binding curve: A: a transition from low-affinity to a high-affinity binding; B: a transition from high-affinity to low-affinity ... bowed timber
