WebNational Center for Biotechnology Information Websampling the mAb peak by a time-based heart cut, the trap column was switched to the flow path of the second dimension using the 2D-LC valve. An aqueous TCEP solution enabled the reduction, while it also allowed the mAb to be retained on the reversed-phase trap column. TCEP is a reducing agent that is easily soluble and stable in aqueous solutions.
