描述

The EIF4A1 protein is an ATP-dependent RNA helicase and an important subunit of the eIF4F complex, which is essential for cap recognition and promoting the binding of mRNA to ribosomes. In the translation initiation model, EIF4A1 helps unravel RNA secondary structure in the mRNA 5'-UTR. EIF4A1 Protein, Human is the recombinant human-derived EIF4A1 protein, expressed by E. coli , with tag free. The total length of EIF4A1 Protein, Human is 406 a.a., .

研究背景

EIF4A2 是一种 ATP 依赖性 RNA 解旋酶,作为 eIF4F 复合物的关键亚基,在帽子识别和促进 mRNA 与核糖体结合方面发挥关键作用。在流行的翻译起始模型中,EIF4A2 有助于解开 mRNA 5'-UTR 中存在的 RNA 二级结构。这种解旋活性对于小核糖体亚基的有效结合以及随后扫描起始密码子(翻译起始的基本过程)至关重要。

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
