Web15 nov. 2012 · The characteristic Rg/Rh value for a globular protein is ~0.775, which means that Rg is smaller than Rh. However, when molecules deviate from globular to non-spherical or elongated structures then Rg/Rh tend to values upwards of 0.775, as Rg becomes larger than Rh. Experimentally, it is important to remember that for proteins Rg …

Web20 apr. 2024 · Determination of R s by SEC has been widely used to monitor conformational changes induced by the binding of calcium (Ca 2+) to many Ca 2+ -sensor proteins. For this class of proteins, SEC separation is based not just on the variation in protein size following Ca 2+ binding, but likely arises from changes in the hydration shell structure. Web6 apr. 2024 · This means that the hydrated radius is the radius of ions when surrounded by water molecules.
