This project has led to an improvement of ChromaCon’s MCSGP technology for purification of ADC’s. It also improved Alphalyse’s analytical methods for detailed antibody drug conjugates characterization and their drug-antibody-ratios (DAR). The developed analytical tools are beneficial for ChromaCon as well as other biopharmaceutical companies developing ADC’s and monoclonal antibodies (mAbs).
Antibody drug conjugates (ADCs) are site-directed monoclonal antibodies (mAbs) coupled to highly potent cytotoxins with great potential for targeted treatment of various types of cancer. The drug-antibody-ratio (DAR) is important for the dosing, but difficult to control in manufacturing and analytical characterization.
The analysis method for antibody drug conjugates characterization includes DAR profiling. UV LC-MS/MS determines the MW of the intact ADC, and of ADC subunits generated by IdeS cleavage.
