    The umbilical cord blood of 47 out of 54 normal human infants contains hemagglutinating activity directed toward cells coated with a type-L Bence-Jones protein. This hemagglutinating material, in some instances, is present in cord blood in the absence of such activity in the maternal blood. Ultracentrifugation of cord serum in a sucrose gradient shows that the activity is associated with the macroglobulin fractions.

    Antibody Structure01:10

    Antibody Structure

    Overview
    Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
    The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
    Antibodies consist of four polypeptide chains: two identical heavy...

    Transcytosis of IgG01:15

    Transcytosis of IgG

    Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
    IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
    Hybridoma Technology01:31

    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.

    Development of Immunocompetence01:22

    Development of Immunocompetence

    The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
    The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
    Subsequent T...
