METHOD FOR PRODUCING LOW-MOLECULAR PEPTIDES SHOWING INTERFERON STIMULATING ACTIVITY Russian patent published in 2011 - IPC C12P21/00 C07K1/34

Abstract RU 2409678 C1

FIELD: medicine.

SUBSTANCE: raw material is an ultrafiltration waste in a lactoglobulin process, containing low-molecular peptides. The method involves conducting dialysis on polysulphide membrane filters of pore diametre 1 kDa against distilled water to reach total protein concentration in the preparation 3 mg/ml. The produced preparation is concentrated by ion-exchange gel chromatography. It is followed with elution with 0.5 M aqueous sodium chloride.

EFFECT: method allows producing the concentrated solution of low-molecular peptides showing interferon stimulating activity.
