描述

HA/Hemagglutinin Protein is a type of viral fusion protein. It mediates the fusion of the membrane of endocytosed virus particles with the endosomal membrane, responsible for the penetration of the virus into the cytoplasm. HA/Hemagglutinin Protein binds to sialic acid receptors, allowing the virus particles to attach to cells. HA/Hemagglutinin Protein is a homotrimer consisting of a globular head domain located at the top of the stem domain near the membrane. Hemagglutinin/HA Protein, H11N2 (AAY85533, sf9, His) is the recombinant Virus-derived Hemagglutinin/HA protein, expressed by Sf9 insect cells , with C-His labeled tag.
研究背景

HA/Hemagglutinin 蛋白是一类病毒融合蛋白，通过介导内吞病毒颗粒的膜与内体膜的融合，负责将病毒渗透到细胞质中。HA/Hemagglutinin Protein 介导的膜融合发生在体内且依赖体内的PH值，体内的酸性环境会触发 HA/Hemagglutinin Protein 的构象变化，进而诱导病毒-宿主膜融合。HA/Hemagglutinin Protein 结合唾液酸受体，使病毒颗粒附着在细胞上。HA/Hemagglutinin 蛋白是一种同源三聚体，由位于膜近端茎结构域顶部的球状头结构域组成[1][2]。

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)
× = ×
C1   V1   C2   V2

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
