The effect of anti-CD25 monoclonal antibody (anti-CD25 mAb) on the protection efficacy of Schistosoma japonicum 26 kDa GST (glutathione-S-transferase) vaccine was evaluated. Mice were immunized with GST before infection with S. japonicum cercariae and then injected with anti-CD25 mAb. The worm reduction rate was promoted from 24.18% in mice with GST immunization to 47.09% in …

Adaptation of an ELISA assay for detection of IgG 2a responses against therapeutic monoclonal antibodies in a mouse immunization model

February 15, 2022 0 Comments

Biotherapeutic monoclonal antibodies (mAb) play important roles in clinical medicine but their potential to elicit immune responses in patients remains a major issue. In a study designed to investigate the effect of aggregation on immunogenic responses, mice were immunized with two monoclonal antibodies (mAb1 and mAb2). Serum levels of total IgG, IgG1, and IgG2a were measured …
