Treatment of human Delta-like protein (Dlk-1) antibody with 2-mercaptoethylamine (cleaving hinge-region disulfide bonds between heavy chains of antibody molecules) and conjugation of half antibodies to maleimide-activated avidin and purification on a size-exclusion column results in a 200 kDa conjugate
