We describe a modified method for assay of t-aminocaproic acid. Serum or cerebrospinal fluid is deproteinized, followed by cation-exchange column-chromatography, and N-trifluoroacetyl-n-butyl derivativesof amino acids are formed and separatedby gas chromatography.Tranexamic acid,a nonproteinamino acid,was used as an internal standard.The assay issensitiveand precise,and results correlate adequa...
