  2. ELISA - Wikipedia

    en.wikipedia.org/wiki/ELISA

    In the latter case a sandwich ELISA is clearly distinct from an indirect ELISA. When the "primary" antibody is of interest, e.g. in the case of immunization analyses, this antibody is directly detected by the secondary antibody and the term "indirect ELISA" applies to a setting with two antibodies. [citation needed]

  3. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    These enzymes allow for detection often because they produce an observable color change in the presence of certain reagents. In some cases these enzymes are exposed to reagents which cause them to produce light or chemiluminescence. There are several types of ELISA: direct, indirect, sandwich, competitive. [7]

  4. Primary and secondary antibodies - Wikipedia

    en.wikipedia.org/wiki/Primary_and_secondary...

    A primary antibody can be very useful for the detection of biomarkers for diseases such as cancer, diabetes, Parkinson’s and Alzheimer’s disease and they are used for the study of absorption, distribution, metabolism, and excretion (ADME) and multi-drug resistance (MDR) of therapeutic agents.

  5. Radioimmunoassay - Wikipedia

    en.wikipedia.org/wiki/Radioimmunoassay

    After extensive washing, the direct amount of radioactive antibody bound is measured and the amount of target molecule quantified by comparing it to a reference amount assayed at the same time. This method is similar in principle to the non-radioactive sandwich ELISA method. [3]

  6. Immunofluorescence - Wikipedia

    en.wikipedia.org/wiki/Immunofluorescence

    Photomicrograph of a histological section of human skin prepared for direct immunofluorescence using an anti-IgG antibody. The skin is from a patient with systemic lupus erythematosus and shows IgG deposit at two different places: The first is a band-like deposit along the epidermal basement membrane ("lupus band test" is positive).

  8. Lateral flow test - Wikipedia

    en.wikipedia.org/wiki/Lateral_flow_test

    The majority of sandwich assays also have a control line which will appear whether or not the target analyte is present to ensure proper function of the lateral flow pad. [2] The rapid, low-cost sandwich-based assay is commonly used for home pregnancy tests which detect human chorionic gonadotropin, hCG, in the urine of pregnant women.
