| Specificity / Sensitivity | Phospho-AS160 (Ser588) (D8E4) Rabbit mAb recognizes endogenous levels of AS160 protein only when phosphorylated at Ser588. |
| Source / Purification | Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser588 of human AS160 protein. Western Blotting
Western blot analysis of extracts from serum-starved HeLa cells, untreated or treated with hIGF-I #8917 (100 ng/ml, 15 min), using Phospho-AS160 (Ser588) (D8E4) Rabbit mAb (upper) or AS160 (C69A7) Rabbit mAb #2670 (lower). The phospho-specificity of the antibody is verified by λ phosphatase treatment. |
| Background | The polypeptide insulin is a major hormone controlling critical energy functions such as glucose and lipid metabolism. Insulin binds to and activates the insulin receptor (IR) tyrosine kinase, which phosphorylates and recruits different adaptor proteins. The signaling pathway initiated by insulin and its receptor stimulates glucose uptake in muscle cells and adipocytes through translocation of GLUT4 glucose transporter from the cytoplasm to the plasma membrane (1). A 160 kDa substrate of the Akt Ser/Thr kinase (AS160, TBC1D4) is a Rab GTPase-activating protein that regulates insulin-stimulated GLUT4 trafficking. AS160 is expressed in many tissues including brain, kidney, liver, and brown and white fat (2). Multiple Akt phosphorylation sites have been identified on AS160 in vivo , with five sites (Ser318, Ser570, Ser588, Thr642, and Thr751) showing increased phosphorylation following insulin treatment (2,3). Studies using recombinant AS160 demonstrate that insulin-stimulated phosphorylation of AS160 is a crucial step in GLUT4 translocation (3) and is reduced in some patients with type 2 diabetes (4). The interaction of 14-3-3 regulatory proteins with AS160 phosphorylated at Thr642 is a necessary step for GLUT4 translocation (5). Phosphorylation of AS160 by AMPK is involved in the regulation of contraction-stimulated GLUT4 translocation (6).

文献和实验：使用 Anti-phospho-Akt (Ser473) Rabbit mAb 对石蜡包埋的人乳腺癌组织进行免疫组织化学分析。（图 A）使用免疫组化试剂盒M&R HRP/DAB Detection IHC Kit，抗体 1:100 稀释；(图 B) 采用普通免疫组化试剂盒，抗体 1:25 稀释。 图 6 免疫组化实验检测 Erk1/2 表达 注：使用 Anti-Erk1/2 Mouse mAb与p44/42 MAPK （Erk1/2）Rabbit mAb 对正常小鼠心脏组织进行免疫
(Ser473)(193H12)Rabbit mAb，1:300,稀释，二抗是驴抗兔，1：2000，我是实验室的新手，刚呆俩月，受 此挫折，一头雾水，请过来人或者有经验的同学帮忙解答怎样解决，非常感谢！ 碧峤 pAkt有两个位点，Ser473和Thr308，其中Ser473相对容易显色。如果显色失败，可能的原因:1 上样量过少，我们一般都是30μg；2 一抗孵育时间过短，我们一般24h~48h；3 一抗是否工作有待排除 米宝
TBS 和 5% NGS 中封闭样品。市售的含有酪蛋白的封闭溶液与磷酸化的一抗结合后易减弱信号；因此，我们建议不使用含有酪蛋白的封闭剂进行磷酸化特异性抗体的检测。以上针对封闭步骤所提建议均是在以 SignalStain. Boost IHC Detection Reagent 作为检测试剂的情况下提出的。如果选择使用其他检测试剂，我们则建议使用与二抗来源相同的血清进行封闭。抗体：Phospho–Histone H2A.X (Ser139) (20E3) Rabbit mAb #9718样本：石蜡
