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。
Blocking is a critical step for controlling nonspecific background in immunoassays such as Western Blot, ELISA, IHC, and IF, but the targets of blocking are not completely identical among different experiments. BSA, Casein, and protein-free blocking solutions are mainly used to limit nonspecific ...
High molecular weight western blotting is a modification of the standard western blotting technique specifically designed for the detection and analysis of large molecular weight proteins.
Immunoprecipitation of natural proteins is a classic method for studying natural protein interactions, which relies on the specific binding between antibodies and proteins (antigens). This technique can be used to qualitatively detect proteins, determine the physiological role of proteins in ...
Blue native polyacrylamide gel electrophoresis (BN-PAGE) is an electrophoretic technique used to separate and analyze large protein complexes. It preserves protein complexes in their native state under non-denaturing conditions by treating samples with mild detergents and negatively charged dyes ...
This method provides a recipe of lysate and buffer preparation for lysing cells or tissues for western blot analysis.
Western blotting is a technique that uses specific antibodies to separate proteins and is widely used to analyze the expression of specific proteins in cell or tissue extracts. This protocol details the steps for performing western blotting of cell culture and tissue samples using both ...
Polyclonal, monoclonal, and recombinant antibodies are all suitable for western blotting. Polyclonal antibodies are a collection of many monoclonal antibodies that can vary between immunizations and batches. Polyclonal antibodies recognize multiple epitopes of an antigen and are therefore ...
Since the first publication describing Western blotting, this immunodetection technique has been widely used to identify specific proteins in complex mixtures extracted from cells or tissues.
免疫印迹是研究蛋白质功能和定位的常用技术。通常，蛋白质样品可在SDS-PAGE上分离并转印至硝酸纤维素膜(NC膜)或PVDF膜上，然后用特异性抗体进行检测。与可重复利用Southern和Northern印迹的核酸技术不同，免疫印迹很难重复使用。 ...
