Enzyme Linked Immunosorbent Assay - StatPearls - NCBI Bookshelf
2023年4月23日 · Enzyme-linked immunosorbent assay (ELISA) is a heterogeneous EIA technique used in clinical analyses.[1] In this type of assay, one of the reaction components is nonspecifically adsorbed or covalently bound to the surface of a solid phase, such as a microtiter well, a magnetic particle, or a plastic bead.
Overview of ELISA | Thermo Fisher Scientific - US
ELISA (enzyme-linked immunosorbent assay) is a plate-based assay technique designed for detecting and quantifying soluble substances such as peptides, proteins, antibodies, and hormones. Other names, such as enzyme immunoassay (EIA), are also used to describe the same technology.

酶联免疫吸附测定 （enzyme-linked immunosorbent assay，ELISA）又称 酵素免疫分析法，簡稱 酶联法 、 酶免[1]，是利用 抗原 抗體 之間 專一性鍵結 之特性，對檢體進行檢測的分析方法；由於結合於固體承載物 (一般為塑膠孔盤)上的抗原或抗體仍可具有 免疫活性，因此設計其鍵結機制後，配合酵素呈色反應，即可顯示特定抗原或抗體是否存在，並可利用呈色的深淺進行定量分析 [2][3]。 酶联法的一项重要应用为用于HIV检测，其检测的蛋白一般为HIV的p24蛋白 (P24 …
What is an ELISA? - Abcam
ELISA stands for enzyme-linked immunosorbent assay, also often referred to as enzyme immunoassay (EIA). An ELISA, like other types of immunoassays, relies on antibodies to detect a target antigen using highly specific antibody-antigen interactions. In an ELISA assay, the antigen must be immobilized to a solid surface.
ELISA - Wikipedia
ELISA has been used as a diagnostic tool in medicine, plant pathology, and biotechnology, as well as a quality control check in various industries. In the most simple form of an ELISA, antigens from the sample to be tested are attached to a surface. Then, a matching antibody is applied over the surface so it can bind the antigen.
Enzyme-linked immunosorbent assay (ELISA) - Microbe Notes
2022年5月17日 · ELISA Principle. Antigens and antibodies react specifically to form the Ag-Ab complex. Antibodies can be linked or attached to enzymes. The enzyme-linked antibodies can modify the specific substrates used to produce a color change within the preparation.
ELISA- Definition, Principle, Procedure, Types, Steps, Applications
2022年8月7日 · ELISA (enzyme-linked immunosorbent assay) is a technique for detecting the presence of antigens in biological materials. An ELISA, like other types of immunoassays, uses antibodies to detect a target antigen via highly specific antibody-antigen interactions.
How Does ELISA Work? - Cell Signaling Technology
Because of the specificity of the antibody reagents and the simplicity of the test, an ELISA is typically considered as the gold standard for quantitative testing of biologic samples. Tests that use the ELISA principle of antibody-antigen binding with amplification of signal are ubiquitous in the biomedical/biochemical fields.
Enzyme-Linked Immunosorbent Assay: Types and Applications
2023年2月17日 · Enzyme-linked immunosorbent assay (ELISA) is an immunological technique extensively used in research and clinical laboratory settings to quantitatively identify a specific protein (i.e., the antigen or biomarker) in a biological matrix while relying on the principle of the specific binding interaction between the antigen and the antibody ...
