Western Blot(蛋白质免疫印迹)是分子生物学中用于检测特定蛋白质表达的关键技术。其原理基于SDS-PAGE电泳分离蛋白质,再通过转膜将蛋白转移到固相载体(如PVDF膜),最后利用抗体特异性结合目标蛋白并进行显影分析。该方法广泛应用于疾病研究、药物开发和基础科研,具有高特异性和灵敏度,是验证基因表达和蛋白功能的重要工具。
实验流程主要包括样品制备、电泳分离、转膜、抗体孵育和信号检测。每一步需严格控制条件,如蛋白浓度、抗体效价和封闭时间,以确保结果准确性。Western Blot技术虽操作复杂,但通过标准化步骤和严谨优化,可稳定获得可靠数据,为生命科学研究提供有力支持。| 品名 | CAS | 货号 |
