Solvent affinity
WebJun 25, 2024 · Poorly hydrogen bonded solvents have maximal absorption capacity, thus toluene has a high affinity with Paraloid ® and evaporates slowly. Inversely, strongly hydrogen bonded ethanol has minimal absorption capacity, low affinity, and low solubility in Paraloid ® B72 (it is actually insoluble in Paraloid ® B44), enabling it to evaporate more … WebSmall scale affinity purification using an antibody immobilized to a solid support.
