    摘要: The invention provides processes for preparing a cell-binding agent chemically coupled to a drug. A first process comprises covalently attaching a linker to a cell-binding agent, an optional purification step, conjugating a drug to the cell-binding agent, a subsequent purification step, and optional holding steps. A second process comprises covalently attaching a linker to a cell-binding agent, a purification step, conjugating a drug to the cell-binding agent, a subsequent purification step. holding steps, and optionally a tangential flow filtration (TFF) step.
