Method and composition for quantitative determination of ammonia, . alpha. -amino acid, or amp;agr;-keto acid

摘要

The present invention is directed to a method for the quantitative determination of ammonia, an &agr;-amino acid and an &agr;- keto acid corresponding to the &agr;-amino acid, or a chemical substance producing any one of these compounds. The present invention is also directed to an analytical composition for use in the above method. The method of the present invention ensures rapidness and accuracy in the determination of ammonia, &agr;-amino acids or &agr;-keto acids, even with the use of a small quantity of a biological sample. This method is very useful in application fields, such as clinical diagnosis and food testing.
