Description
Details
Description:Mouse monoclonal antibody to human platelet membrane glycoprotein IIb/IIIa (GP IIb/IIIa)
Purification:Protein G affinity purified
Product Type: Primary antibody
Target Protein:Human platelet membrane glycoprotein IIb/IIIa
Immunogen:Human platelet suspension
Fusion Myeloma:Sp2/0-Ag14
Specificity:The mAb reacts with human platelet.
Species Reacitvity:Human, others not tested
Host / Isotype:Mouse, IgG1 Kappa
Formulation:Lyophilized from a solution in 0.01M PBS, pH 7.2
Reconstitution:Double distilled water is recommended to adjust the final concentration to 1.00mg/mL.
Storage: Store at -20oC
Research Area:Hematology, blood coagulation
Background:
Human platelet membrane glycoprotein Glycoprotein IIb/IIIa (GP IIb/IIIa) is a dominate receptor on the platelet membrane with very high molecular weight (>200kDa). After the platelet is activated, the GP IIb/IIIa receptor complex changes conformation and binds to fibrinogen in blood circulation with high affinity. The activation of platelets is initiated locally when the endothelial layer is wounded and the platelets are exposed to the collagen underneath the endothelium. The fibrinogen aggregates with platelets when binding to the GP IIb/IIIa receptor on platelets, thus primary haemostasis (Platelet clot) is formed.
Application:
ELISA:The mAb is reactive to platelet coated ELISA plate.
Western Blot: The antibody reacts strongly with high molecular weight protein on blot transferred with gel separated platelet membrane glycoproteins.

不加磷酸化抑制剂也可以做磷酸化蛋白WB,但是有可能会影响具体的实验结果,大部分时候不加磷酸化抑制剂也能得到结果的。
需要注意蛋白的磷酸化是一个非常迅速的反应,所以取样品的过程要迅速,样品要新鲜。
所以做磷酸化蛋白WB,提取蛋白时不加磷酸酶抑制剂会有影响
酶抑制剂新药发现的途径:一是来源于天然化合物,包括动植物和各种微生物等,二是化学合成物。在目前上市的药物中,以受体为作用靶点的药物占52%,以酶为靶点的药物占22%,以离子通道为靶点的药物占6%,以核酸为靶点的药物占3%。因此,酶抑制剂的开发是新药来源的一个主要途径。以酶为靶点开发新药存在巨大潜力,今后很长一段时间仍然是发现新药的重要着手点。

Abstract:The Notch signaling pathway represents a critical component in the molecular circuits that control cell fate during development. Aberrant activation of this pathway contributes to tumorigenesis. The role of Notch in human cancer has been highlighted recently by the presence of activating mutations and amplification of Notch genes in human cancer and by the demonstration that genes in the Notch signaling pathway could be potential therapeutic targets. It has become clear that one of the major therapeutic targets in the Notch pathway are the Notch receptors, in which gamma-secretase inhibitors prevent the generation of the oncogenic (intracellular) domain of Notch molecules and suppress the Notch activity. This review article summarizes the biological roles of Notch molecules in cancer development with special emphasis on the promise and challenges in applying gamma-secretase inhibitors as a new line of targeted therapeutic agents.
