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. La invención proporciona métodos para cuantificar un tensioactivo no iónico en una composición que comprende un polipéptido y el tensioactivo no iónico, donde la cuantificación muestra interferencia reducida entre el tensioactivo no iónico y el polipéptido. También se proporcionan métodos donde la composición incluye además N-acetiltriptófano y la cuantificación muestra interferencia reducida entre el tensioactivo no iónico, el polipéptido y N-acetiltriptófano.
