Biochemical characterization of the AffiDCs.

Conjugate	Purity a (%)	Calc. MW (Da)	Found b MW (Da)
ZHER2:2891-ABD-E3-mcDM1	>95	14,383.8	14,383.3
ZHER2:2891-ABD-G3-mcDM1	>95	14,167.6	14,167.3
(ZHER2:2891)2-ABD-E3-mcDM1	>95	21,393.6	21,393.0
ZHER2:2891-ABD-E3-AA	>95	13,597.4	13,597.0

^a The purity was measured from the area under curve in the chromatograms in Figure 1D. ^b The molecular weights were determined by ESI-TOF mass spectrometry (Figure S1).
