Conventional lysine- or cysteine-based conjugation results in heterogeneous ADC products due to a wide drug-to-antibody ratio(DAR) distribution. Over the last decade, many site-specific conjugation technologies have been developed to address this issue, yet the improved homogeneity usually comes at a cost. To address these issues, WuXi XDC developed WuXiDAR2™, WuXiDAR4™ and WuXiDAR6™, collectively referred to as the WuXiDARx technology platform.
