Determination of amino acids as 2,4-dinitrophenyl derivatives. Serine and lysine.
1. Serine and lysine in complicated mixtures, such as protein hydrolysates, are dinitrophenylated quantitatively, isolated chromatographically and determined. 2. The method is accurate, moderately rapid and suitable for a number of estimations in parallel, but uses only normal laboratory apparatus.
