  2. Antigen - Wikipedia

    en.wikipedia.org/wiki/Antigen

    An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the molecular structure of an antigen. In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. [1]

  3. Antigen-antibody interaction - Wikipedia

    en.wikipedia.org/wiki/Antigen-antibody_interaction

    The first correct description of the antigen-antibody reaction was given by Richard J. Goldberg at the University of Wisconsin in 1952. [1] [2] It came to be known as "Goldberg's theory" (of antigen-antibody reaction). [3] There are several types of antibodies and antigens, and each antibody is capable of binding only to a specific antigen.

  4. Diego antigen system - Wikipedia

    en.wikipedia.org/wiki/Diego_antigen_system

    The Diego antigen (or blood group) system is composed of 21 blood factors or antigens carried on the Band 3 glycoprotein, also known as Anion Exchanger 1 (AE1).The antigens are inherited through various alleles of the gene SLC4A1 (Solute carrier family 4), located on human chromosome 17.

  5. History and naming of human leukocyte antigens - Wikipedia

    en.wikipedia.org/wiki/History_and_naming_of...

    It was found that some antigens that behaved like A and B antigens but could be excluded based on '2-type max' exclusion. Thus a new group, "C" was created. Classification of C antigens is still ongoing, and they have retained the name Cw as many serotypes have not been developed. The classification of the "A4" antigens was complicated.

  6. Immunolabeling - Wikipedia

    en.wikipedia.org/wiki/Immunolabeling

    Immunolabeling - Antigen Detection of Tissue via Tagged Antigen-specific Antibody. Immunolabeling is a biochemical process that enables the detection and localization of an antigen to a particular site within a cell, tissue, or organ. Antigens are organic molecules, usually proteins, capable of binding to an antibody.

  7. Polyclonal B cell response - Wikipedia

    en.wikipedia.org/wiki/Polyclonal_B_cell_response

    The immune system may respond in multiple ways to an antigen; a key feature of this response is the production of antibodies by B cells (or B lymphocytes) involving an arm of the immune system known as humoral immunity. The antibodies are soluble and do not require direct cell-to-cell contact between the pathogen and the B-cell to function.

    The antigens expressed by tumors have several sources; [134] some are derived from oncogenic viruses like human papillomavirus, which causes cancer of the cervix, [135] vulva, vagina, penis, anus, mouth, and throat, [136] while others are the organism's own proteins that occur at low levels in normal cells but reach high levels in tumor cells.
