An improved colorimetric method for the determination of proline in the presence of other ninhydrin-positive compounds

J J Wren 1, P H Wiggall 1
PMCID: PMC1206430  PMID: 14342233

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.
