  2. Organization and expression of immunoglobulin genes

    en.wikipedia.org/wiki/Organization_and...

    Antibody (or immunoglobulin) structure is made up of two heavy-chains and two light-chains. These chains are held together by disulfide bonds. The arrangement or processes that put together different parts of this antibody molecule play important role in antibody diversity and production of different subclasses or classes of antibodies.

  3. List of therapeutic monoclonal antibodies - Wikipedia

    en.wikipedia.org/wiki/List_of_therapeutic...

    This list of over 500 monoclonal antibodies includes approved and investigational drugs as well as drugs that have been withdrawn from market; consequently, the column Use does not necessarily indicate clinical usage. See the list of FDA-approved therapeutic monoclonal antibodies in the monoclonal antibody therapy page.

  4. Antibody - Wikipedia

    en.wikipedia.org/wiki/Antibody

    Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.

  5. Immunoglobulin heavy chain - Wikipedia

    en.wikipedia.org/wiki/Immunoglobulin_heavy_chain

    Each heavy chain has two regions: a constant region (which is the same for all immunoglobulins of the same class but differs between classes).. Heavy chains γ, α and δ have a constant region composed of three tandem (in a line next to each other) immunoglobulin domains but also have a hinge region for added flexibility.

  6. Polyclonal antibodies - Wikipedia

    en.wikipedia.org/wiki/Polyclonal_antibodies

    Polyclonal antibodies (pAbs) are antibodies that are secreted by different B cell lineages within the body (whereas monoclonal antibodies come from a single cell lineage). ). They are a collection of immunoglobulin molecules that react against a specific antigen, each identifying a different ep

  7. Immunoglobulin superfamily - Wikipedia

    en.wikipedia.org/wiki/Immunoglobulin_superfamily

    In humans, there are five distinct types of immunoglobulin molecule all containing a heavy chain with four Ig domains and a light chain with two Ig domains. The antigen receptor of T cells is the T-cell receptor (TCR), which is composed of two chains, either the TCR-alpha and -beta chains, or the TCR-delta and gamma chains.

  8. Framework region - Wikipedia

    en.wikipedia.org/wiki/Framework_region

    Antibody humanization is an example of beneficial genetic engineering in medicine today. [10] Humanized antibody refers to the creation of non-human antibody in vivo and in response to antigen, then the isolation and humanization of the framework and constant regions. It has been discovered that while these antibodies remain relatively intact ...

  9. Abzyme - Wikipedia

    en.wikipedia.org/wiki/Abzyme

    If an antibody is developed to bind to a molecule that is structurally and electronically similar to the transition state of a given chemical reaction, the developed antibody will bind to, and stabilize, the transition state, just like a natural enzyme, lowering the activation energy of the reaction, and thus catalyzing the reaction.
