Patent ID: 8236927

Claim:
A method for producing an aqueous albumin solution from a starting albumin solution which contains stabilizer molecules which are capable of occupying binding sites of the albumin, by removing at least a portion of the stabilizer molecules from the starting albumin solution comprising the steps of: a) bringing the starting albumin solution into contact with a solid adsorption material having an affinity for at least a portion of the stabilizer molecules that is higher than the affinity of the albumin for the corresponding stabilizer molecules at a pH ≧5; wherein the adsorption material is a particulate activated charcoal material packed in a column or a bed or a support matrix so that fluid-carrying channels are formed between the particles of adsorption material, wherein the mean diameter of the channels, relative to the total length of the channels formed between particles of all of the adsorption material employed, is more than 100 nm and less than 1000 μm; and b) separating the albumin from the adsorption material.
