 Similar to Gerlough, the Precipitate A, which is equivalent to Cohn’s Fraction II and III, was done at a lower ethanol concentration of 19%, but the pH, in this case, was also lower to 5.85.Also similar to Gerlough and Mulford, the fraction IV was combined and precipitated at conditions of 40% ethanol, pH of 5.85, and temperature of −8 degrees C. The albumin, which is recovered in fraction V, is recovered in Precipitate C at a pH adjustment to 4.8.Similar to the Cohn Process, the albumin is purified by extraction into water followed by precipitation of the impurities at 10% ethanol, pH 4.6, and −3 degrees C. Akin to the Cohn Process, the precipitate formed here is filtered out and discarded.
