SAR408701, NAB, DM4 and MeDM4 molecular weight

Entity Molecular weight (g/mol)
SAR408701 150,000*
NAB 144,522
DM4 780
MeDM4 794

*SAR408701 molecular weight varies slightly as a function of DAR, but it was assumed that each drug conjugate contributed to a negligible amount of the global molecular weight. The 150,000 g/mol molecular weight used for SAR408701 was an average molecular weight determined for an ADC with three [linker-DM4] complexes attached to the antibody
