Abstract
The use of X-ray photoelectron spectroscopy (XPS) for the analysis of protein adsorption on materials relevant to biomanufacturing of protein drug products is explored. Details of the methods used to obtain three pieces of information about protein adsorption on materials relevant to bioprocessing will be described: I) confirmation of protein adsorption, II) an estimate of how much protein is adsorbed and III) the conformational state (native or denatured) of the protein on the surface.Citation
