从细胞膜、胞浆到细胞核，存在多条信号通路串联交叉形成的复杂信号网络。该信号网络在细胞受到胞外刺激后将信号通过级联放大、分散调节等方式传入胞内，引起一系列的综合性细胞应答。一种生物效应的出现往往存在多条信号通路的同步活化，可逆的磷酸化修饰反应则是细胞内部最为普遍和节能的信号蛋白活化调节方式。因此，找到激活的信号通路乃至发生磷酸化调变的通路蛋白，往往成生命科学研究的起点。                

信号通路磷酸化广谱筛选抗体芯片（PEX100），采用三维高分子膜专利技术，在片基上高密度结合  1318  种高特异抗体，分别检测432个信号蛋白的679个磷酸化位点。这些信号蛋白广泛参与多条重要信号通路信号传导过程。芯片针对每一个特定蛋白磷酸化位点，设置一对抗体分别检测其磷酸化（Phospho）和非磷酸化（non-Phospho）状态以提高磷酸化检测灵敏度和稳定性。一次芯片实验即可实现多条信号通路的同步筛选和具体调变位点的清晰定位，为后续生物现象的深入探索提供明确的研究方向。                

芯片特点：                

• 1. 芯片规格为76 x 25 x 1 mm；
