生物活性

Lorigerlimab (MGD019) is a bispecific IgG4 dual-affinity re-targeting antibody (DART). Lorigerlimab can block PD-1 and CTLA-4, and improves T-cell responses. Lorigerlimab can be used for research of metastatic castration-resistant prostate cancer (mCRPC)[1][2][3].

体外研究
(In Vitro)

Lorigerlimab (0.01 nM-1 nM) 与 Jurkat/PD-1 细胞结合并阻断 PD-L1 与细胞结合[2]
Lorigerlimab 可以独立地参与和阻断表达一种或另一种检查点分子的细胞上的 PD-1CTLA-4 (EC50: PD-1+ 细胞为 0.42 nM,CTLA-4+ 细胞为 4.8 nM, PD-1 和 CTLA-4+ 细胞为 0.013 nM)[2]

体内研究
(In Vivo)

Lorigerlimab (75 mg/kg,静脉注射) 在食蟹猴中显示出 CTLA-4 阻断作用[2]
Lorigerlimab (10-100 mg/kg,静脉注射,4 周) 在食蟹猴中耐受性良好,半衰期约为 7 天[2]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
