描述

Ebola virus glycoproteins (GPs) play a key role in the virus entry process, with GP1 serving as the receptor-binding subunit and GP2 for membrane fusion. GP downregulates host cell surface molecules, disrupts adhesion and may lead to disruption of vascular integrity. Ebola virus Glycoprotein/GP Protein RBD (Q05320, HEK293, His) is the recombinant Virus-derived Ebola virus Glycoprotein/GP protein RBD, expressed by HEK293 , with C-His labeled tag.

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至关重要的作用,其中 GP1 充当受体结合亚基,GP2 充当膜融合亚基。在感染后期,GP下调各种宿主细胞表面分子的表达,包括整合素,如ITGA1、ITGA2、ITGA3、ITGA4、ITGA5、ITGA6、ITGAV和ITGB1,破坏细胞粘附并导致细胞脱离,可能导致血管完整性破坏和出血。GP 还与宿主 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。此外,GP可以抵消宿主BST2/tetherin的抗病毒作用,与VP40和宿主BST2合作激活经典的NF-kappa-B通路,并作为抗GP1,2抗体的诱饵,有助于病毒免疫逃避。此外,GP 与宿主巨噬细胞和树突状细胞相互作用并激活它们,通过激活宿主 TLR4 诱导细胞因子转录上调。

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
