AGO2/Argonaute-2 蛋白, Mouse (sf9, His, solution)

目录号: HY-P74423Y
COA 产品使用指南

AGO2/Argonaute-2 蛋白对于 RNA 介导的沉默复合物 (RISC) 介导的基因沉默至关重要。在“最小RISC”中,AGO2 与短引导RNA(例如microRNA (miRNA) 或短干扰RNA (siRNA))结合,以引导RISC 与互补mRNA 一起沉默。AGO2/Argonaute-2 蛋白, Mouse (sf9, His, solution) 是重组的 AGO2/Argonaute-2 蛋白,由 Sf9 insect cells 表达,带有 N-His 标签。

描述

The AGO2/Argonaute-2 protein is critical for RNA-mediated silencing complex (RISC)-mediated gene silencing. In "minimal RISC," AGO2 binds to short guide RNAs, such as microRNAs (miRNAs) or short interfering RNAs (siRNAs), to guide RISC for silencing with complementary mRNAs. AGO2/Argonaute-2 Protein, Mouse (sf9, His, solution) is the recombinant mouse-derived AGO2/Argonaute-2 protein, expressed by Sf9 insect cells , with N-His labeled tag.

研究背景

AGO2 是 RNA 介导的基因沉默 (RNAi) 中的关键参与者,由 RNA 诱导的沉默复合物 (RISC) 协调,对于多种调控过程是不可或缺的。“最小 RISC”配置涉及 AGO2 与短向导 RNA(例如 microRNA (miRNA) 或短干扰 RNA (siRNA))连接,指导 RISC 靶向 mRNA 进行沉默。沉默机制取决于指导RNA与其靶mRNA之间的互补性。完美互补促进 AGO2 介导的核酸内切切割,而部分互补则独立于核酸内切酶活性抑制翻译。AGO2 可以通过与 7-甲基鸟苷帽结合,阻碍 eIF4-E 募集,或通过与 EIF6 相互作用,阻止核糖体亚基的结合来阻碍翻译起始。这种翻译抑制导致 mRNA 在细胞质加工体(P 体)中积累,最终可能导致 mRNA 降解。值得注意的是,AGO2 通过在不同的生长条件下抑制和促进翻译而表现出多功能性。此外,AGO2 是转录基因沉默 (TGS) 不可或缺的一部分,其中短 RNA(例如反基因 RNA)指导互补启动子区域的抑制。在微生物感染的情况下,AGO2 与病毒 miRNA 样小 RNA(例如 Sars-CoV-2 感染期间的 CoV2-miR-O7a)相关,可能抑制特定 mRNA(例如 BATF2),以逃避干扰素反应。

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
