NOVEL PROTEIN CONJUGATES AND PROCESS FOR THE PREPARATION THEREOF

摘要

The invention relates to novel protein conjugates of the formulae (1a-c). T he invention further relates to a method for preparing the protein conjugates b y reacting proteins with three low molecular weight components in a single reaction ste p, up to four reporter groups or ligands being introduced simultaneously at a defined stoichiometry and molecular distance and to applications of the novel protei n conjugates.
