SPDB and SMCC linkers used earlier without triggering aggregation or loss of affinity of the resulting conjugate. Antibody–maytansinoid conjugates (AMCs) bearing these sulfonate- or PEG-containing hydrophilic linkers were, depending on the nature of the targeted cells, equally to more cytotoxic to antigen-positive cells and equally to less cytotoxic to antigen-negative cells than conjugates made with SPDB

The invention relates to charged or pro-charged cross-linking moieties and conjugates of cell binding agents and drugs comprising the charged or pro-charged cross-linking moieties and method of using the same to reduce ocular toxicity associated with administration of antibody drug conjugates.
This invention describes a method of conjugating a cell binding agent such as an antibody with an effector group (e.g., a cytotoxic agent) or a reporter group (e.g., a radionuclide), whereby the reporter or effector group is first reacted with a bifunctional linker and the mixture is then used without purification for the conjugation reaction with the cell binding agent. The method described in this invention is advantageous for preparation of stably-linked conjugates of cell binding agents, such as antibodies with effector or reporter groups. This conjugation method provides in high yields conjugates of high purity and homogeneity that are without inter-chain cross-linking and inactivated linker residues.
