描述

Ebola virus glycoprotein (GP1), as a receptor-binding subunit, plays a key role in the virus entry process. During late stages of infection, GP1 downregulates key host cell surface molecules, including integrins such as ITGA1-6, disrupting adhesion and potentially leading to disruption of vascular integrity. Ebola virus Glycoprotein/GP Protein (Q7T9D9, sf9, His) is the recombinant Virus-derived Ebola virus Glycoprotein/GP protein, expressed by Sf9 insect cells , with C-His labeled tag. The total length of Ebola virus Glycoprotein/GP Protein (Q7T9D9, sf9, His) is 637 a.a., with molecular weight of ~67.9 kDa.

研究背景

埃博拉病毒糖蛋白 (GP) 的三聚体 GP1,2 复合物在病毒进入过程中发挥着关键作用,其中 GP1 充当受体结合亚基,GP2 充当膜融合亚基。在感染的后期,GP1 下调参与免疫监视和细胞粘附的关键宿主细胞表面分子的表达。这包括整合素的调节,如 ITGA1、ITGA2、ITGA3、ITGA4、ITGA5、ITGA6、ITGAV 和 ITGB1,可能导致细胞脱离并导致血管完整性破坏,从而导致感染期间出血(细胞毒性)。此外,GP1 与宿主 TLR4 相互作用,刺激单核细胞的分化和激活,导致 T 淋巴细胞的旁观者死亡。它进一步下调宿主自然杀伤细胞的功能,并抵消宿主 BST2/tetherin 的抗病毒作用,从而限制子代病毒粒子从受感染的细胞中释放。有趣的是,GP1 与 VP40 和宿主 BST2 合作,以依赖于 neddylation 的方式激活典型的 NF-kappa-B 通路。此外,GP1 作为抗 GP1,2 抗体的诱饵,有助于病毒免疫逃避,并与宿主巨噬细胞和树突状细胞相互作用,诱导细胞因子转录上调,这种效应是通过激活宿主 TLR4 介导的。

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.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
