Abstract: Methods for the large scale preparation of clinical albumin are disclosed. One method includes dilution of plasma with a NaCl solution containing disodium ethylene dinitrilo tetraacetate and a stabilizer such as sodium caprylate. The resulting solution is then subjected to heating and cooling steps, followed by the addition of polyethylene glycol to precipitate impurities, with albumin remaining in the supernatant. Isoelectric precipitation is then employed to recover the desired albumin product, which is devoid of the albumin dimer. In an alternative method, ethanol is employed as the precipitating agent rather than polyethylene glycol.
