额外eIF抗体，包括eIF1, eIF1AY, eIF2 α, eIF2B α, eIF2B β, eIF2B δ, eIF2B ε, eIF2 β, eIF2B γ, eIF2C, eIF2C2, eIF2C4, eIF2D, eIF3 p110, eIF3 α和eIF3 β

eIF2C2抗体（4F9）是一种IgA κ小鼠单克隆eIF2C2抗体（也称为EIF2C2抗体、AGO2抗体或Argonaute 2抗体），可通过免疫沉淀（IP）、免疫荧光（IF）和酶联免疫吸附测定（ELISA）检测来自小鼠、大鼠和人类的eIF2C2蛋白。eIF2C2抗体（4F9）为非偶联的抗eIF2C2抗体形式。真核翻译起始因子2C（eIF2C）蛋白（Argonaute家族）作为RNA诱导沉默复合体（RISC）或含有microRNA（miRNA）的核糖核蛋白颗粒（miRNP）的组成部分，影响RNA干扰（RNAi）。小RNA，包括小干扰RNA（siRNA）和miRNA，可以通过利用RISC或miRNP颗粒的机制来沉默靶基因。eIF2C1（Argonaute 1，AGO1，eIF2C，GERP95，Q99）和Dicer1在siRNA介导的基因沉默中起协同作用。eIF2C2（Slicer，Argonaute 2，AGO2，Q10）是RISC的一个组成部分，可以集中在细胞质处理体（P-bodies）中并催化mRNA裂解。哺乳动物P-bodies含有mRNA，并与miRNA诱导的翻译沉默和siRNA诱导的mRNA降解有关。其他eIF2C蛋白还包括eIF2C3（Argonaute 3，AGO3）、eIF2C4（Argonaute 4，AGO4）和meIF2c5（小鼠Argonaute 5）。

Hi. I'm writing you from Bronner's lab, CALTECH. We want to know if this antibody recognize Chick Ago2. Thanks

Asked by: Estefanía
Thank you for your question. Unfortunately we do not have any information regarding chicken reactivity, so we can not recommend it for that use.

Rated 2 out of 5 by from Poor band visibility in WBThis antibody was used at 1:500 dilution. The bands obtained were not very clear (in visibility or number) even at high exposition times. You can still assess the general protein quantity on WB but I recommend maybe to dilute it less.

Rated 2 out of 5 by from Not suitable for WBWe wanted to detect Ago2 in our sample via WB. So unfurtunatley for our purpose this AB did not work. Nevertheless it is also mentioned in the describtion to use another AB for detection.
