GCN2, or General Control Nonderepressible-2, is a kinase belonging to the protein kinase family. It is known for its ability to phosphorylate the alpha subunit of the eukaryotic translation initiation factor 2 (eIF2α), thereby downregulating protein synthesis under various cellular stress conditions. GCN2 is activated in response to amino acid deprivation and binds to uncharged tRNAs, and it may also be activated under conditions of glucose deprivation and viral infections. Phosphorylated GCN2 (phospho T899) is a key regulatory point for the kinase activity of GCN2. When GCN2 is phosphorylated at the Thr899 site, it can more effectively phosphorylate Ser51 of eIF2α, which in turn inhibits global protein translation rates and reduces the consumption of amino acids within the cell. This mechanism makes GCN2 an important sensor and regulator in the cellular response to amino acid starvation and other stress conditions. In the tumor microenvironment, the activation of GCN2 is associated with the modulation of immune responses. Studies have shown that the activation of GCN2 can lead to T cell anergy and apoptosis, enhance myeloid-derived suppressor cell (MDSC)-dependent immunosuppression, and promote tumor cell survival. Therefore, the inhibition of GCN2 may have direct anti-cancer effects and immune-activating effects, making it a potential therapeutic target for cancer treatment.

IHC shows positive staining in paraffin-embedded mouse liver and negative staining in mouse liver treated with phosphatase. Anti- Phospho-GCN2 (T899) antibody was used at 1/200 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

FAQs
我们一般不推荐客户回收利用抗体。 因为抗体使用之后缓冲体系已经发生改变,不同客户在回收抗体的保存条件上也会有差异,所以抗体回收使用效果无法保证。另外,我们对一批抗体回收验证测试,测试结果显示不同抗体可回收次数不同,一般效价越高的抗体,可重复使用的次数越多,客户可根据实验情况来确定
我们推荐客户使用TPST+5%脱脂奶粉来稀释一抗,进行封闭。 虽然BSA被推荐为WB检测磷酸化蛋白的常用封闭剂,但是脱脂奶粉获取更加方便,覆盖更广泛的非特异性结合位点,在一抗性能优越的前提下,使用脱脂奶粉封闭性价比更高
