1. A method of producing a population of recombinant polypeptides, comprising:
providing a target value of C-terminal variants of a recombinant polypeptide, providing a host cell comprising a nucleic acid encoding the recombinant polypeptide, culturing the host cell under conditions (i) in which the cell expresses a population of C-terminal variants of the encoded recombinant polypeptide and (ii) which increase the intracellular pH of the cell, and isolating the population, wherein the population comprises the provided target value of C-terminal variants of the recombinant polypeptide. |
