Obexelimab (XmAb5871) is a humanized anti-CD19 antibody. Obexelimab works by inhibiting B cell receptor (BCR) mediated calcium influx and promoting the phosphorylation of Fc γ receptor IIb (FcγRIIb), which reduces B cell activation and function, leading to B cell apoptosis. Obexelimab can be used in research for rheumatoid arthritis and systemic lupus erythematosus.

Anti-Mouse CD19 Antibody (1D3) is an IgG2a antibody inhibitor targeting mouse CD19. Anti-Mouse CD19 Antibody (1D3) reduces CD19 expression levels on the surface of B cells. Anti-Mouse CD19 Antibody (1D3) inhibits the replication of peritoneal B-1a cells.

Denintuzumab (hBU 12) is a recombinant humanized anti-CD19 monoclonal antibody. Denintuzumab binds to CD19 on the surface of B cells. Denintuzumab can be used as the antibody moiety (ADC antibody) of antibody-drug conjugates to synthesize ADC, Denintuzumab Mafodotin (SGN-CD19A). Denintuzumab Mafodotin can be used in the research of acute lymphoblastic leukemia.

Englumafusp alfa (CD19-4-1BBL; RO7227166) is a fusion construct comprised of a CD19-specific antibody domain fused to a trimerized extracellular domains of human 41BBL. Englumafusp alfa promotes CD19-specific 4-1BB cross-linking on the surface of T and NK cells.

LY3541860 is a selective anti-CD19 antibody that both binds human CD19 with high affinity and selectively binds human B cells (K_d values: 76.8 pM and 94.5 nM for humans and cynomolgus monkeys, respectively). LY3541860 inhibits CpG-induced CD69 expression (IC₅₀ = 0.006 nM). LY3541860 exhibits potent B cell inhibitory activities. LY3541860 can inhibit both BCR- and TLR-induced human B cell activation. LY3541860 can be used for the research of autoimmune diseases.

Anti-CD19 Antibody (4G7) is an anti-human CD19 IgG1 monoclonal antibody. Anti-CD19 Antibody (4G7) reduces the killing effect of CAR T cells on Raji cells. Anti-CD19 Antibody (4G7) can be used for research on immunology. Anti-CD19 Antibody (4G7) is often used in flow cytometry. The recommend isotype control of Anti-CD19 Antibody (4G7): Mouse IgG1 kappa, Isotype Control (HY-P99977).

Coltuximab is a CHO-expressed humanized antibody that targets CD19. Coltuximab is composed of huIgG1 heavy chains and huκ light chains, with a molecular weight (MW) of 144.70 kDa. The isotype control for Coltuximab can refer to Human IgG1 kappa, Isotype Control (HY-P99001).

The Anti-CD19 Antibody is a humanized antibody expressed in CHO cells, targeting CD19. The Anti-CD19 Antibody contains a huIgG1 heavy chain and a huκ light chain, with a predicted molecular weight (MW) of 145 kDa. The isotype control for Anti-CD19 Antibody can be referenced as Human IgG1 kappa, Isotype Control (HY-P99001).

GBR-401 is a humanized anti-CD19 monoclonal antibody with high affinity for FcγRIIIa. GBR-401 exerts a potent in vitro and in vivo cytotoxic activity against various B-cell malignancies. GBR-401 induces cell death by antibody dependent cellular cytotoxicity (ADCC) and direct killing effect. GBR-401 demonstrates potent activity of depleting malignant B cells and prolongs mice survival in multiple xenograft severe combined immunodeficiency (SCID) mice models.

IASO-782 (RD126) is a fully human monoclonal antibody targeting human CD19. The Fc segment of IASO-782 is mutated to enhance antibody-dependent cell-mediated cytotoxicity (ADCC) while maintaining the integrity of other Fc segment functions, such as ADCP. IASO-782 effectively eliminates CD19+ B cells, plasmablasts, and some plasma cells, thereby reducing or completely eliminating autoreactive antibodies produced by these cells. IASO-782 can be used for the study of immune thrombocytopenic purpura (ITP), warm autoimmune hemolytic anemia (wAIHA) and systemic lupus erythematosus (SLE).
