    Immobilized Concanavalin A-Sepharose 4B (CSB) binds myeloma immunoglobulins (IgG through IgE) in larger proportions than it binds normal immunoglobulins. Some possible explanations for this are discussed. Also, CSB shows differential affinity among immunoglobulins, normal or myelomatous; its greatest affinity is for IgM and IgE. This property can be used to separate a large percentage of the IgM and IgE from both normal and myelomatous sera.

    Immunoglobulin-like Cell Adhesion Molecules

    Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
    Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

    Hybridoma Technology

    Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.
