  2. Ring vaccination - Wikipedia

    en.wikipedia.org/wiki/Ring_vaccination

    Ring vaccination is a strategy to inhibit the spread of a disease by vaccinating those who are most likely to be infected. [ 1 ] This strategy vaccinates the contacts of confirmed patients, and people who are in close contact with those contacts.

  3. Recombination-activating gene - Wikipedia

    en.wikipedia.org/wiki/Recombination-activating_gene

    The enzymatic activity of the RAG proteins is concentrated largely in a core region; Residues 384–1008 of RAG-1 and residues 1–387 of RAG-2 retain most of the DNA cleavage activity. The RAG-1 core contains three acidic residues (D 600 , D 708 , and E 962 ) in what is called the DDE motif , the major active site for DNA cleavage.

  4. Radial immunodiffusion - Wikipedia

    en.wikipedia.org/wiki/Radial_immunodiffusion

    [1] [2] The diameter of the circle increases with time as the antigen diffuses into the medium, reacts with the antibody, and forms insoluble precipitin complexes. [ 1 ] [ 2 ] [ 5 ] The antigen is quantitated by measuring the diameter of the precipitin circle and comparing it with the diameters of precipitin circles formed by known quantities ...

  6. 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.

  7. Original antigenic sin - Wikipedia

    en.wikipedia.org/wiki/Original_antigenic_sin

    The original antigenic sin: When the body first encounters an infection it produces effective antibodies against its dominant antigens and thus eliminates the infection. But when it encounters the same infection, at a later evolved stage, with a new dominant antigen, with the original antigen now being recessive, the immune system will still produce the former antibodies against this old "now ...

  8. Ouchterlony double immunodiffusion - Wikipedia

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

    Antibodies have at least two antigen binding sites (and in the case of immunoglobulin M there is a multimeric complex with up to 10 antigen binding sites), thus large aggregates or gel-like lattices of antigen and antibody are formed. Experimentally, an increasing amount of antigen is added to a constant amount of antibody in solution.

  9. Peptide vaccine - Wikipedia

    en.wikipedia.org/wiki/Peptide_vaccine

    The peptides mimic the epitopes of the antigen that triggers direct or potent immune responses. [1] Peptide vaccines can not only induce protection against infectious pathogens and non-infectious diseases but also be utilized as therapeutic cancer vaccines , where peptides from tumor-associated antigens are used to induce an effective anti ...
