CHROMATOGRAPHY METHOD FOR QUANTIFYING A NON-IONIC SURFACTANT IN A COMPOSITION COMPRISING THE NON-IONIC SURFACTANT AND A POLYPEPTIDE

The invention provides methods for quantifying a non-ionic surfactant in a composition comprising a polypeptide and the non- ionic surfactant, where the quantification exhibits reduced interference between the non-ionic surfactant and the polypeptide. Also provided are methods where the composition...

Beschreibung
Zusammenfassung:	The invention provides methods for quantifying a non-ionic surfactant in a composition comprising a polypeptide and the non- ionic surfactant, where the quantification exhibits reduced interference between the non-ionic surfactant and the polypeptide. Also provided are methods where the composition further includes N-acetyl tryptophan, and the quantification exhibits reduced interference between the non- ionic surfactant, the polypeptide, and N-acetyl tryptophan. L'invention concerne des procédés de quantification d'un tensioactif non ionique dans une composition comprenant un polypeptide et le tensioactif non ionique, la quantification présentant une interférence réduite entre le tensioactif non ionique et le polypeptide. L'invention concerne également des procédés selon lesquels la composition comprend en outre du N-acétyl tryptophane, et la quantification présente une interférence réduite entre le tensioactif non ionique, le polypeptide et le N-acétyl tryptophane.
