产品详情	Patritumab (Human Anti-ERBB3 Recombinant Antibody) 是针对 ERBB3 的中和性单克隆抗体。Patritumab与 Cetuximab (HY-P9905) 具有协同作用，可有效抑制 EGFR，HER2，HER3，ERK 和 AKT 的磷酸化。Patritumab 也能诱导细胞凋亡 (apoptosis)，也抑制胰腺、非小细胞肺癌和结直肠癌异种移植物肿瘤的生长。
生物活性	Patritumab (Human Anti-ERBB3 Recombinant Antibody) is a neutralizing monoclonal antibody to ERBB3. Patritumab shows a synergy with Cetuximab (HY-P9905), potently inhibits the phosphorylation of EGFR, HER2, HER3, ERK, and AKT. Patritumab also induces cell apoptosis and suppresses the growth of pancreatic, non-small cell lung cancer, and colorectal cancer xenograft tumors.
性状	Liquid
体外研究(In Vitro)	Patritumab targets to the extracellular domain (ECD) of HER3 and (10 μg/mL; 5 d) induces DiFi-HRG4 cells apoptosis. Patritumab (10 μg/mL; 6 h) markedly inhibits the phosphorylation of HER3 and AKT, without affecting that of ERK, in DiFi-HRG4 cells. Patritumab (10 μg/mL; 48 h) also induces the cleavage of PARP accompanied with both up-regulation of BIM and down-regulation of survivin expression. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)	Patritumab (1 mg/mouse; i.p.; twice a week for 4 weeks) combines with 1 mg Cetuximab and restores Cetuximab sensitivity in DiFi-HRG tumor xenografts model in mice. Heregulin produced by colorectal cancer tumors harboring wild-type KRAS induces Cetuximab resistance, and that combination therapy with cetuximab and patritumab overcomes such resistance in vivo. has not independently confirmed the accuracy of these methods. They are for reference only.

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
