Red colored IgG4 caused by vitamin B12 from cell culture media combined with disulfide reduction at harvest.

abstract：:Fragmentation in the hinge region of an IgG1 monoclonal antibody (mAb) can affect product stability, potentially causing changes in potency and efficacy. Metals ions, such as Cu(2+), can bind to the mAb and undergo hydrolysis or oxidation, which can lead to cleavage of the molecule. To better understand the mechanism ...
