用于检测、定量和定位抗原与抗体的技术——ELISA、免疫印迹、免疫组化与流式细胞术。以下是我们知识库中标注该主题的实验方案、常见问题与技术文章。
Electrophoresis buffers determine sample migration speed, band resolution, heat generation, and subsequent recovery efficiency. When selecting a buffer, it is necessary to first distinguish whether the sample is DNA, RNA, or protein, and then determine the buffer system according to the target ...
电泳缓冲液决定样品迁移速度、条带分辨率、发热程度和后续回收效果。选择时应先区分DNA、RNA还是蛋白样品，再根据目标分子大小、凝胶类型、是否变性、是否回收和后续检测方式确定缓冲体系。

Common Questions and Answers for SDS-PAGE Experiments
The primary function of β-mercaptoethanol is to selectively cleave disulfide bonds in protein molecules—chemical bonds that are critical for maintaining the protein’s spatial conformation. Once disrupted, these bonds cause partial dissociation of the protein’s secondary and higher-order ...
巯基乙醇的核心功能是靶向断裂蛋白质分子中的二硫键——这种对维持蛋白质空间构象至关重要的化学键一旦断裂，会使蛋白质的二级及以上高级结构发生初步解聚；而SDS则会进一步破坏蛋白质分子内部的氢键、疏水键、离子键等非共价键，促使原本折叠的肽链逐渐伸展，实现高级结构的彻底瓦解。 ...
Polyacrylamide gel electrophoresis (PAGE) is an electrophoretic technique that employs polyacrylamide gel as the supporting matrix. The core principle lies in the molecular sieving effect of the gel’s network structure, which enables precise separation of proteins and nucleic acids based on ...

蛋白印迹实验 (WB) 广泛用于分析细胞或组织提取物中的特异性蛋白表达。蛋白印迹实验很耗时，而且它们的成功对研究进展有着重要影响。
Protein blotting (WB) is widely used to analyze the expression of specific proteins in cell or tissue extracts. Western blot experiments are time-consuming, and their success has a significant impact on research progress.
Protein dephosphorylation is an important biochemical process in cells, involving the removal of phosphate groups from specific amino acid residues on proteins. This process corresponds to protein phosphorylation, and the two together form a dynamic balance that is crucial for cell signal ...
蛋白质去磷酸化是细胞内一个重要的生化过程，涉及从蛋白质上的特定氨基酸残基上去除磷酸基团。该过程与蛋白质磷酸化相对应，两者共同形成对细胞信号转导至关重要的动态平衡。蛋白质磷酸化和去磷酸化作为一对可逆的生化反应，通过“分子开关”的方式，精细调控蛋白质的结构、功能以及细胞内的多种生理活动。 ...
The Interleukin (IL) family is a group of cytokines and development factors mainly derived from white blood cells, which play a key role in coordinating the immune response.
白细胞介素(Interleukin, IL)家族是一组主要来源于白细胞的细胞因子和生长因子，在协调免疫应答中起关键作用。
