  2. Ouchterlony double immunodiffusion - Wikipedia

    en.wikipedia.org/wiki/Ouchterlony_double_immuno...

    Ouchterlony double immunodiffusion (also known as passive double immunodiffusion) is an immunological technique used in the detection, identification and quantification of antibodies and antigens, such as immunoglobulins and extractable nuclear antigens.

  3. Immunodiffusion - Wikipedia

    en.wikipedia.org/wiki/Immunodiffusion

    Immunodiffusion is a laboratory technique used to detect and quantify antigens and antibodies by observing their interactions within a gel medium. [1] This technique involves the diffusion of antigens and antibodies through a gel, usually agar, resulting in the formation of a visible precipitate when they interact.

  4. Radioimmunoassay - Wikipedia

    en.wikipedia.org/wiki/Radioimmunoassay

    A radioimmunoassay (RIA) is an immunoassay that uses radiolabeled molecules in a stepwise formation of immune complexes.A RIA is a very sensitive in vitro assay technique used to measure concentrations of substances, usually measuring antigen concentrations (for example, hormone levels in blood) by use of antibodies.

  5. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    An immunoassay (IA) is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes).

  6. Radial immunodiffusion - Wikipedia

    en.wikipedia.org/wiki/Radial_immunodiffusion

    A solution containing antibody is added to a heated medium such as agar or agarose dissolved in buffered normal saline.The molten medium is then poured onto a microscope slide or into an open container, such as a Petri dish, and allowed to cool and form a gel.

  7. Immunoelectrophoresis - Wikipedia

    en.wikipedia.org/wiki/Immunoelectrophoresis

    Counter-immunoelectrophoresis and its modification. In comparison to other conventional methods of diagnosis e.g. for viral infection testing, counter-immunoelectrophoresis is a highly specific, simple, and speedy method that does not require sophisticated, expensive tools, input materials, or long-term capacity building.

  8. Complement fixation test - Wikipedia

    en.wikipedia.org/wiki/Complement_fixation_test

    A schematic of a complement fixation test. The complement fixation test is an immunological medical test that can be used to detect the presence of either specific antibody or specific antigen in a patient's serum, based on whether complement fixation occurs.

  9. Örjan Ouchterlony - Wikipedia

    en.wikipedia.org/wiki/Örjan_Ouchterlony

    Örjan Thomas Ouchterlony (January 14, 1914, Stockholm – September 25, 2004) was a Swedish bacteriologist and immunologist who is credited with the creation of the Ouchterlony double immuno diffusion test in the 1940s. [1] [2] He was trained at Karolinska Institute, where his received his medical doctorate.
