Tarlatamab (AMG-757) is a bispecific T-cell engager (BiTE) antibody targeting delta-like ligand 3 (DLL3). DLL3 is a target that is selectively expressed in small-cell lung cancer (SCLC) tumors, but with minimal normal tissue expression. Tarlatamab has the K_Ds of 0.64 nM and 0.50 nM for human and nonhuman primate (NHP) DLL3, respectively. Tarlatamab has the K_Ds of 14.9 nM and 12 nM for human and NHP CD3, respectively. Tarlatamab is a first-in-class HLE BiTE immuno-oncology therapy targeting DLL3 and has the potential for SCLC research.

Bimagrumab (Anti-ACVR2B Reference Antibody) is a human monoclonal antibody that blocks activin type II receptor (ActRII), with K_Ds of 1.7 pM and 434 pM for human ActRIIB and ActRIIA, respectively. Bimagrumab can be used for the research of pathological muscle loss and weakness.

Nivolumab is a programmed death receptor-1 (PD-1) blocking human IgG4 antibody to treat advanced (metastatic) non-small cell lung cancer.

Tocilizumab (Anti-Human IL6R, Humanized Antibody) is an anti-human interleukin-6 receptor (IL-6R) neutralizing antibody, prevents binding of IL-6 to the IL-6R, thereby inhibiting both classic and trans-signaling. Tocilizumab (Anti-Human IL6R, Humanized Antibody) can be used for the treatment of rheumatoid arthritis. Tocilizumab is remarkablely effective for the study of severe COVID-19 (coronavirus disease).

Infliximab (Avakine) is a chimeric monoclonal IgG1 antibody that specifically binds to TNF-α. Infliximab prevents the interaction of TNF-α with TNF-α receptor (TNFR1 and TNFR2). Infliximab has the potential for autoimmune, chronic inflammatory diseases and diabetic neuropathy research.
The component ratio of this product is Active ingredient : Excipients = 9 : 47.

Tulisokibart (PRA023) is a humanized IgG1-κ monoclonal antibody. Tulisokibart targets to TNFSF15/TL1A. Tulisokibart can be used to study a variety of inflammatory/fibrotic diseases, such as Crohn's Disease (CD) and ulcerative colitis.

Amivantamab (JNJ-61186372) is a human EGFR-MET bispecific antibody with immune anticancer activity. Amivantamab inhibits ligand binding, promotes endocytosis and degradation of receptor-antibody complexes, and induces Fc-dependent cytokinesis in macrophages and antibody-dependent cytotoxicity in natural killer cells.

Trontinemab (RG6102) is a brain-penetrant, anti-amyloid, bispecific and humanizedized IgG1-κ antibody, targeting to Aβ plaques and transferrin receptor 1 (TFR1). Trontinemab binds to fibrillar Aβ as well as Aβ plaques triggering plaque clearance by engaging immune cells on Alzheimer disease (AD) brain sections. Trontinemab also shows specific affinity to cynomolgus and human TFR1.

Teclistamab is a human bispecific antibody to BCMA and CD3 that recognizes BCMA on target cells and CD3 on T cells and induces T cell-mediated cytotoxicity leading to T cell activation and subsequent target cell lysis. Teclistamab can be used in studies of diseases related to multiple myeloma (MM).
