Rapid photometric method for the determination of taurine and cysteic acid.
A method is described for the rapid determination of microgram quantities of taurine or cysteic acid in the presence of relatively large amounts of other amino-acids. Dinitrophenylation of the sample followed by chloroform extraction yields an aqueous solution containing only DNP-taurine or DNP-cysteic acid, the absorbance of which gives a direct measure of these components.
