СПОСОБ ОПРЕДЕЛЕНИЯ СОДЕРЖАНИЯ СВОБОДНЫХ АМИНОКИСЛОТ-ЛИЗИНА И/ИЛИ МЕТИОНИНА- В КОРМОВЫХ СРЕДСТВАХ

摘要

FIELD: biotechnology, amino acids. ^ SUBSTANCE: invention relates, in particular, to a method for analysis of fodder agents, fodder supplements and other preparations comprising lysine and methionine. For determination of the content of free amino acids lysine and/or methionine in fodder agents method involves preparing fodder agents solutions and amino acids in prepared extracts are converted to their dansyl derivatives, and their content in solution is determined by method of capillary electrophoresis. By obtained data the content of free lysine and methionine is calculated in analyzed sample of the fodder agent. Method provides rapid and reliably determination of the content of free lysine and methionine in fodder agents. ^ EFFECT: improved assay method. ^ 3 cl
