•Abstract: What Is An Antibody? An antibody is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects like bacteria and viruses. Each antibody recognizes a specific antigen unique to its target. This is because at the two tips of its "Y", it has...
One reason for this is that they eliminate the risk of non-specific binding to Fc receptors on immune cells due to not having an Fc region. In addition, the smaller size of antibody fragments allows them to enter cells and tissues more easily than whole antibody molecules, making them ...

IgM is involved in the initial immune response to an infection, and is one of the first antibody isotypes produced by B lymphocytes when they first become activated. IgM is also capable of triggering the complement cascade. IgD is known to be involved in the early life cycle of B lymphocyte...
"IgE" stands for the protein immunoglobulin E. In an allergic person, this antibody is released as part of the body's immune response to what it mistakenly views as a harmful substance (ie, pollen, mold, or food particles). IgE antibodies are specific to individual allergens; theCM Calson...
There are no preparations that a person needs to take before an antibody titer is administered. The procedure involves drawing blood from a vein, normally on the back of the hand or the inside of the elbow. In infants or younger children, a lancet might be used. There are virtually no he...
A serumantibodyis an antibody derived from serum, a blood component that is collected after blood has coagulated. As it is collected aftercoagulation,blood serumdoes not actually contain blood cells orclotting factors. It does, however, include many different types of proteins that are not involved...
What is an Antibody? What is a Natural Killer Cell? Discussion Comments By aaaCookie — On Dec 21, 2010 @behaviourism, that is another good example. While antibiotics, immunizations, and other preventative measures seem like a good idea, they can backfire. Antibiotics are only good against...
such as Alzheimer's disease. Carefully controlled primary antibodies will bind to a very specific antigen, and scientists can use this knowledge to detect exactly what types of antigens are found in the body of a sick person. It also shows if an antibody is functioning improperly and attacking...
