Mosunetuzumab
Based on 1 publication(s) in Google Scholar
Mosunetuzumab (BTCT-4465A) is a full-length, fully humanized immunoglobulin G1 (IgG1) T-cell-dependent bispecific (TDB) antibody targeting CD20 (B cells) and CD3 (T cells). Mosunetuzumab redirects T cells to engage and eliminate malignant B cells and can be used for the research of relapsed or refractory (R/R) B-cell non-Hodgkin lymphomas (B-NHLs). The Fc region of Mosunetuzumab incorporates a "knob-into-hole" structural modification and an N297G point mutation to achieve heterodimerization and eliminate Fc glycosylation, thereby effectively silencing antibody effector functions.

In Vitro
Mosunetuzumab has two arms. One arm binds specifically to CD3 on T-cells and the other to CD20 present on normal and neoplastic B-cells. Simultaneous binding of both arms to their respective targets facilitates T-cell-mediated killing of CD20+ B-cells[2].

Flow cytometric analysis of 1X106 Raji cells with Mosunetuzumab (HY-P99033, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black). -
