METHOD OF FREE GENE-CODED AMINO ACID SEPARATION

摘要

FIELD: chemistry. ^ SUBSTANCE: invention concerns separation of free gene-coded amino acid mix by method of capillary electrophoresis and can be applied in quality control for medicines and in defining amino acid composition of bioactive peptides. Sodium dihydrophosphate solution with methanol (pH 1.9-2.1) added is proposed as background electrolyte. Analysis is performed at +9-+11 kV voltage. The result is enhanced selectivity of free gene-coded amino acid separation leading to complete separation of 16 amino acid mix. ^ EFFECT: possibility of amino acid analysis of bioactive peptides. ^ 1 cl, 1 ex, 2 tbl
