Mab fragmentation
WebMar 24, 2024 · Several fragmentation patterns for mAbs have been reported, including disulfide bond disruption, prone peptide hydrolysis containing Asp residue, chemical or protease hydrolysis in the hinge region, and other cleavage routes favored by specific temperature, chemical and pH conditions [5], [6], [7], [8], [9]. WebJan 21, 2024 · To induce a detectable amount of Asp-Pro cleavage in a large protein, we chose the therapeutic mAb rituximab, which was incubated in 250 mM ammonium acetate buffer (pH 4) at 40 °C for 138 h. The only Asp-Pro motif in the sequence of rituximab is in the Fc region (Fig. S5).
