描述

HA/hemagglutinin protein binds to sialic acid receptors and promotes viral attachment. It triggers internalization through clathrin-dependent or independent pathways. HA/Hemagglutinin Protein, H9N2 (Q9ICY5, 317a.a, HEK293, His) is the recombinant Virus-derived HA/Hemagglutinin protein, expressed by HEK293 , with C-His labeled tag.

研究背景

HA蛋白与细胞表面含有唾液酸的受体结合,促进病毒颗粒附着到细胞上。这种附着通过网格蛋白依赖性内吞作用或通过网格蛋白和小窝蛋白独立途径触发病毒的内化。HA蛋白对于确定病毒的宿主范围限制和毒力至关重要。作为I类病毒融合蛋白,它负责介导内吞病毒颗粒膜与内体膜的融合,使病毒渗透到细胞质中。在内体的低pH环境下,HA2发生不可逆的构象变化,导致融合疏水肽的释放。需要多个HA三聚体才能形成有能力的融合孔。

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
