DETERMINATION OF PROTEIN CONCENTRATION IN A FLUID

Abstract:

The present disclosure provides systems and methods that allow users to quickly determine titer and remove hold steps by determining a first concentration using slope spectroscopy, depleting the fluid of the expressed protein by selective adsorption, and determining a second concentration using slope spectroscopy. Further, the systems and methods of the present disclosure allows the user to forgo the use of a bioanalyzer or HPLC.
