The present disclosure relates to methods and materials for determining an isoelectric point for a protein including, for example, a binding molecule such as an antibody. The isoelectric points may be used in methods for the preparation of proteins. Such methods may comprise identifying amino acid residues that are exposed on the surface of the protein in a sequence of amino acid residues of the protein, assigning a pKa value to the surface exposed amino acid residues, and calculating the isoelectric point of the protein from the pKa values assigned to the surface exposed amino acid residues. The methods of the present disclosure may be used for selecting and utilizing a buffer for purification of a protein, preparing a protein formulation, purifying a protein and/or stabilizing a protein in solution. |
