Fuente: WIPO "milk" The invention relates to an anti-inflammatory factor, in substantially pure form, produced by a process comprising: (i) removing the fat from milk of a milk-producing animal to produce skimmed milk; (ii) removing casein from said skimmed milk to produce whey; (iii) removing from said whey macromolecules having a molecular weight greater than about 10,000 daltons; (iv) fractionating the low-molecular weight product from the previous step by ion exchange chromatography; (v) further purifying the anti-inflammatory factor from the previous step by molecular sieve chromatography; and (vi) collecting said anti-inflammatory factor; a method of isolating a substantially pure anti-inflammatory factor from milk comprising the steps (i)-(vi) as above described and the substantially pure anti-inflammatory factor from milk comprising an oligomeric carbohydrate.
