  3. OSE-279

OSE-279 是一种靶向 PD-1 的高亲和力人源化双价单克隆抗体,推荐的同型对照为 HY-P99003。OSE-279 可阻断 PD-1 的配体结合,抑制 PDL1 诱导的 SHP1 磷酸化,恢复 T 细胞活化,并促进原代 T 细胞效应功能的再激活。OSE-279 可结合 hFcRn 受体,具有长半衰期潜力,可诱导 CD4 和 CD8 T 细胞增殖,并促进白细胞介素 2 (IL-2) 和干扰素 γ 的分泌。OSE-279 可用于晚期恶性肿瘤、结肠癌、肝癌、间皮瘤的研究。

生物活性

OSE-279 is a high-affinity humanized monoclonal bivalent antibody targeting PD-1, the recommended isotype control is HY-P99003. OSE-279 blocks PD-1 ligand binding, inhibits PDL1-induced SHP1 phosphorylation, restores T cell activation, and promotes reactivation of primary T cell effector functions. OSE-279 binds hFcRn receptor, predicts long half-life, induces CD4 and CD8 T cell proliferation, and promotes interleukin 2 and interferon gamma secretion. OSE-279 can be used for the research of advanced malignancies, colon cancer, hepatocarcinoma, mesothelioma[1][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.
