It is possible to use IgMBRAZOR with low concentrations of IgM. However, this will lead to a decreased reaction rate, so for IgM concentrations below 0.5 mg/mL it is recommended to increase the amount of added enzyme and/or increase the incubation time. There is no risk of overdigestion and the incubation time can be prolonged to overnight if necessary.

Yes, IgMBRAZOR and PNGase F can be used in combination if the reaction is performed under non-denaturing conditions. However, for complete deglycosylation of IgM using PNGase F denaturing conditions may be required and it is then recommended to perform the IgMBRAZOR digestion prior the PNGase F deglycosylation.
