蛋白电泳是一种分离和分析蛋白的关键技术，通过电场作用使蛋白在凝胶中移动，实现大小、电荷异同的分子分离。这种方法可用于研究蛋白结构、检测蛋白含量、验证蛋白纯度，并帮助鉴定疾病标志物。蛋白电泳广泛应用于分子生物学、生物化学和临床研究领域，为科学家提供了深入探索蛋白功能和相互作用的有效手段。

Protein electrophoresis is a key technology for separating and analyzing proteins. It uses an electric field to move proteins in a gel to separate molecules with similar sizes and different charges. This method can be used to study protein structure, detect protein content, verify protein purity, and help identify disease markers. Protein electrophoresis is widely used in the fields of molecular biology, biochemistry and clinical research, providing scientists with an effective means to deeply explore protein functions and interactions.
