PubMedPubMed 产品介绍The PDGF Receptor Type A (Alpha platelet-derived growth factor receptor precursor, CD140a antigen), a 170kD protein, binds all three isoforms of PDGF with high affinity whereas the PDGF Receptor Type B, a 190kD protein, appears to bind only the PDGF BB homodimer with high affinity. Both receptors are transmembranous, ligand activated protein tyrosine kinases, which phosphorylate a number of important signal transduction proteins, which are bound with differential affinities via SH2 domains. The response of any given cell to PDGF will depend on the types of receptors displayed on the surface and isoforms of PDGF present in the extracellular environment. 靶点与功能
外周蛋白(Peripheral Membrane Protein)是通过非共价键(静电作用、氢键) 可逆结合于细胞膜表面或内膜系统的蛋白质,与整合膜蛋白的区别在于可通过高盐/碱性溶液洗脱。其核心功能包括: 信号转导:如G蛋白α亚基(Gα)通过结合GPCR参与跨膜信号传递; 细胞骨架锚定:血影蛋白(Spectrin)连接细胞膜与肌动蛋白,维持红细胞形态; 酶活性调控:蛋白激酶C(PKC)通过Ca²⁺依赖的膜结合激活下游通路; 疾病关联:外周蛋白异常与遗传性球形红细胞增多症(血影蛋白缺陷)、肿瘤转移(黏着斑激酶异常) 密切相关。 实验操作关键要点
外周蛋白提取与WB检测: 提取方法:采用低盐缓冲液(10mM Tris-HCl pH7.4) 裂解细胞,10000g离心10分钟取上清(胞质外周蛋白);或用0.5M NaCl溶液洗脱膜结合外周蛋白(需保留整合膜蛋白沉淀作为对照); 抗体孵育:血影蛋白抗体1:1500稀释(5% BSA+TBST),4℃孵育过夜,曝光时间60秒(高分子量条带需延长转膜时间至3小时)。 IF膜定位验证: 样本处理:Hela细胞用4%多聚甲醛固定15分钟,0.1% Triton X-100透化5分钟(保留外周蛋白结合); 共定位标记:与膜整合蛋白抗体(如Na⁺/K⁺-ATP酶)共染,激光共聚焦观察外周蛋白在膜表面的点状/线性分布。 IP实验注意事项: 缓冲液选择:使用含150mM NaCl的IP缓冲液(避免高盐破坏外周蛋白-膜结合),抗体用量3μg/500μg总蛋白; 阴性对照:设置空白beads组(无抗体)和非特异性IgG组,排除非特异性结合。 公司正在出售的产品
