Rapid Removal of IgG1 Carryover on Protease Column Using Protease-Safe Wash Solutions Delivered with LC Pump for HDX-MS Systems.

Sample carryover is a common problem in hydrogen-deuterium exchange mass spectrometry, particularly because immobilized protease columns cannot withstand the high organic solvent concentrations typically used in liquid chromatography-mass spectrometry (LC-MS) for cleaning. Conventional cleaning methods using injections of guanidine HCl still suffer from carryover and may require four blanks after each sample run to fully remove carryover. We have implemented an additional LC pump to deliver customized wash solutions to protease and enzyme columns, and the associated LC capillaries to eliminate carryover.
