背景介绍
SMAD2, also named as MADH2 and MADR2, belongs to the dwarfin/SMAD family, contains 1 MH1 (MAD homology 1) domain and 1 MH2 (MAD homology 2) domain. SMAD2 is a receptor-regulated SMAD(R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta and activin type 1 receptor kinases. This protein may act as a tumor suppressor in colorectal carcinoma. It is phosphorylated on one or several of Thr-220, Ser-245, Ser-250, and Ser-255. In response to TGF-beta, It is phosphorylated on Ser-465/467 by TGF-beta and activin type 1 receptor kinases, and then able to interact with SMURF2, recruiting other proteins, such as SNON, for degradation. In response to decorin, the naturally occurring inhibitor of TGF-beta signaling, it is phosphorylated on Ser-240 by CaMK2. It is phosphorylated by MAPK3 upon EGF stimulation; which increases transcriptional activity and stability, and is blocked by calmodulin. In response to TGF-beta, it is ubiquitinated by NEDD4L, which promotes its degradation. In response to TGF-beta signaling, it is acetylated on Lys-19 by coactivators, which increases transcriptional activity. The molecular weight of unphosphorylated forms of Smad2 is 52 kDa and phosphorylated forms of Smad2 is 58 kDa. (PMID: 9006934)

文献和实验下调不能说明活性降低，因为决定GSK3-beta的活性的还与其磷酸化的比例和磷酸化的位点有关。所以你除了要做GSK3-beta总的蛋白表达之外，还要做磷酸化的GSK3-beta的蛋白表达。 （2）应该活性形式和非活性形式都做。一般来讲，GSK3-beta在Ser9位点磷酸化之后活性收到抑制，而在216位点磷酸化之后，其活性收到加强。因此建议将GSK3-beta的两个磷酸化位点都做了，另外还要同时检测GSK3-beta的总蛋白表达，这样才能全面的说明问题。
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
