At neutral pH it is biased to the 5-coordinate structure, but at the acidic side of the transition of pKa = 5.5 the 6-coordinate heme becomes dominant. F- was bound to the heme iron at pH 6, but Cl- was bound only at acidic pH. Acidification by HNO3, H2SO4, CH3COOH, HBr, or ...
Tadros [23] defined thixotropy as a reversible time-dependent decrease in viscosity that results from: (a) a spatial rearrangement of molecules or particles in a non-Newtonian system or (b) change of the structure in the system, under an applied shear. Once the yield stress of the internal...
Additionally, the structure of the set-up may also contribute to this phenomenon: the dielectric constant is measured in parallel to the surface. As IgG1 covers almost the entire surface, it will have a great and distinct effect on the dielectric constant. Impedance is measured top-down. This...
