AN IMPROVED COLORIMETRIC METHOD FOR THE DETERMINATION OF PROLINE IN THE PRESENCE OF OTHER NINHYDRIN-POSITIVE COMPOUNDS.

J J WREN, P H WIGGALL.   

Abstract

1. The conditions required for sensitive and specific colorimetric determination of proline with acidified ninhydrin were investigated. 2. A method applicable to protein samples was developed. 3. The only compound found to interfere appreciably was a hydroxyproline.
