免疫沉淀/共沉淀技术 (Immunoprecipitation/Co-Immunoprecipitation, IP/Co-IP) 用于研究蛋白相互作用及复合物组装。通过将抗体与目标蛋白结合，沉淀出蛋白复合物，分析交互作用伙伴。Co-IP 则进一步探究复合物中的多个蛋白相互关系。这些技术可揭示信号通路、细胞调控及蛋白功能等方面的信息，对生物学和医学研究有着广泛的应用。

Immunoprecipitation/Co-Immunoprecipitation (IP/Co-IP) technology is used to study protein interactions and complex assembly. By binding antibodies to target proteins, precipitating protein complexes, and analyzing interacting partners. Co-IP further explores the relationship between multiple proteins in the complex. These technologies can reveal information on signaling pathways, cell regulation, and protein functions, and are widely used in biological and medical research.
