GCN2抗体(F-7)是一种IgG1 κ小鼠单克隆GCN2抗体(也称为EIF2AK4抗体),可通过蛋白质印迹法(WB)、免疫沉淀法(IP)、免疫荧光法(IF)、免疫组织化学法(IHC(P))和酶联免疫吸附测定法(ELISA)检测人源性GCN2蛋白。GCN2抗体(F-7)既可作为非偶联抗GCN2抗体形式提供,也可作为多种偶联形式的抗GCN2抗体提供,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。应激反应蛋白激酶家族包括HRI(血红素调节抑制剂或EIF2AK1)、PKR(EIF2AK2或TIK)、PERK(EIF2AK3)和GCN2(EIF2AK4)。这些蛋白质在Ser 51上磷酸化真核翻译起始因子2α(eIF2α),以调节一般和基因特异性蛋白质合成。磷酸化的eIF2α作为其鸟苷酸交换因子eIF2B的抑制剂。GCN2是一种独特的eIF2α激酶,存在于从酵母到哺乳动物的所有真核生物中。在哺乳动物中,GCN2在肝脏和脑组织中的表达最高。GCN2主要启动eIF2α对紫外线的磷酸化反应,但已显示其在血清饥饿时会增加磷酸化活性。此外,eIF2α上Asp 83被Ala取代会导致GCN2和PKR的磷酸化受损,这表明远端残基对激酶底物识别有贡献。

For the antibody sc-374609 , can I use Pfa 4% to fixe my tissue instead of methanol?

Asked by: Raphael3
Thank you for your question. This antibody sc-374609 is recommended for detection of GCN2 of human origin by Western Blot, IP, Immunocytochemistry on methanol-fixed cells, Immunohistochemistry on acetone-fixed frozen tissue sections, Immunohistochemistry on paraffin-embedded tissue sections fixed with formalin and ELISA. We currently have no data for this antibody for a fixation with pfa. Please contact our Technical Service for additional information.
