Web22 jan. 2024 · For an engineered recycling/sweeping antibody, reduced antigen affinity at pH 6.0 leads to dissociation of the antigen from the antibody–antigen complex. The … The Bohr effect hinges around allosteric interactions between the hemes of the haemoglobin tetramer, a mechanism first proposed by Max Perutz in 1970. Haemoglobin exists in two conformations: a high-affinity R state and a low-affinity T state. When oxygen concentration levels are high, as in the lungs, the R state is favored, enabling the maximum amount of oxygen to be bound to the hemes. In the capillaries, where oxygen concentration levels are lower, the T stat…

In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a …

WebAdditionally, in the mutants L2, L4, and L12, the pH 6.0 affinity was further reduced compared to m13. We evaluated the quality of pH-dependent binding by computing the PAR value, i.e., K D at pH 6.0 divided by K D at pH 7.4. A higher value of PAR indicates lower binding affinity at pH 6.0 than at pH 7.4.
