The application of a purification procedure for the industrial preparation from human plasma of a therapeutic protein may be hindered by several safety concerns. The dye leaching from Remazol Yellow GGL-Sepharose used for the affinity chromatography of human plasma transthyretin was quantitatively studied by a sensitive competitive enzyme immunoassay. The possibility of including a heat treatment step for virus inactivation in the purification process while preserving the biochemical and functional characteristics of the protein is also reported.
