ZRC3308-A7

产品介绍

Masavibart (ZRC3308-A7) 是一种靶向SARS-CoV-2的单克隆抗体 (IgG1 型)。Masavibart 对SARS-CoV-2穗状蛋白的RBD上的非竞争性表位显示出良好的结合亲和力。Masavibart 可按 1:1 与 ZRC3308-B10 (HY-145643) 联合使用，对 COVID-19 的预防以及尚未发展为严重疾病的早期 COVID-19 有效。

生物活性

Masavibart (ZRC3308-A7) is ananti-SARS-CoV-2 monoclonal antibody(IgG1 type). Masavibart shows good binding affinity to a non-competing epitope on theRBDof theSARS-CoV-2spike protein. Masavibart can be used in combination withZRC3308-B10(HY-145643) at a ratio of 1:1, which is effective for the prevention of COVID-19 and the early stage of COVID-19 before the development of severe disease^[1].

IC₅₀& Target

SARS-CoV-2^[1].
