Abstract: The invention relates to the purification of peptides from colostrum. The method involves the addition of an alcohol such as methanol or ethanol to the mixture in order to form an alcohol phase rich in the peptides, and a precipitate. The peptide-rich alcohol phase is subsequently recovered and subjected to further fractionation. The invention is particularly useful in the purification of colostrinin from colostrum.

Abstract: The amino acid sequence of several peptides is disclosed. These peptides are useful, inter alia, in the treatment of disorders of the immune system and the central nervous system, and are also useful as food additives.

Abstract: A process for the purification of human interferon alpha involving a three-step chromatography sequence under highly dissociating conditions is disclosed. The purification method involves a first step of loading crude interferon alpha onto a glass sorbent column to adsorb interferon alpha. The adsorbed interferon alpha is then eluted from the glass sorbent using a hydrophobic electrolyte solution comprising tetramethyl ammonium chloride, NaCl and propylene glycol. Thereafter, in a second step, the eluted interferon is subjected to SEPHACRYL S-200 molecular sieving chromatography under highly dissociating conditions and the fractions corresponding to molecular weights ranging from about 10,000 to about 40,000 are collected. In a third step, the collected fractions are then passed thorugh a column Zn++ chelating resin. The interferon alpha passes through unadsorbed to the Zn++ chelating resin.

Abstract: A process for producing unique human interferon gamma and interleukin-2 by chromatographic fractionation utilizing ion exchange and metal chelate chromatography. The interferon gamma and interleukin-2 are purified from crude interferon obtained by mitogen induction of human white blood cells.
