what are monoclonal antibodies and what cells produce them?
203915
Monoclonal antibodies (mAbs) are produced by introducing an antigen to a mouse and then fusing polyclonal B cells from the mouse's spleen to myeloma cells. The resulting hybridoma cells are cultured and continue to produce antibodies to the antigen.

Researchers can design antibodies that specifically target a certain antigen, such as one found on cancer cells. They can then make many copies of that antibody in the lab. These are known as monoclonal antibodies (mAbs or Moabs). Monoclonal antibodies are used to treat many diseases, including some types of cancer.

Immunoglobulins, also known as antibodies, are glycoprotein molecules produced by plasma cells (white blood cells). They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction.

Antibodies are proteins that defend the body against pathogens by binding to antigens on the surface of these pathogens and stimulating their destruction. Antigens are foreign substances which stimulate the production of antibodies. Antibodies usually only bind to one specific antigen. Antibodies are made from B-Cells.

Hybridomas are produced by injecting a specific antigen into a mouse, collecting an antibody-producing cell from the mouse's spleen, and fusing it with a tumor cell called a myeloma cell. The hybridoma cells multiply indefinitely in the laboratory and can be used to produce a specific antibody indefinitely.

Hybridoma is a culture of hybrid cells that results from the fusion of B cells and myeloma cells. ... Hybridomas possess two important properties of B cells, production of antibodies, and immortalization of myeloma cells. MAbs are monospecific antibodies that are produced by a clone of B cells.
986963
humanized monoclonal antibody. A type of antibody made in the laboratory by combining a human antibody with a small part of a mouse or rat monoclonal antibody. The mouse or rat part of the antibody binds to the target antigen, and the human part makes it less likely to be destroyed by the body's immune system.

Hybridomas are hybrid cells produced by the fusion of an antibody-producing lymphocyte with a tumor cell and used to culture continuously a specific monoclonal antibody.

Monoclonal antibodies (mAb or moAb) are antibodies that are made by identical immune cells that are all clones of a unique parent cell. ... In contrast, polyclonal antibodies bind to multiple epitopes and are usually made by several different plasma cell (antibody secreting immune cell) lineages.
1404500
Monoclonal Antibodies are a collection of antibodies that all bind to the same Epitope. ... - Normal immune responses that are caused by Monoclonal Antibodies activate many different B and T cells. Name a normal immune response that activates many different B and T cells activated by Monoclonal Antibodies.
466680
Monoclonal Antibodies recognize and bind to antigens in order to discriminate between specific epitopes which provides protection against disease organisms. ... Fusion of cell culture myeloma cells with mammalian spleen cells antibodies result in hybrid cells/hybridomas which produces large amounts of monoclonal antibody.

In vitro Methods In the in vitro method, antibodies are produced using the hybridoma method, where hybridoma cells are generated by fusing myeloma cells and B-lymphocytes. These lymphocytes may be from a mouse or rat. The target antigen is injected to the animal, and thus the animal is immunized against the antigen.

B lymphocytes or B cells produce antibodies involved in humoral immunity. B cells are produced in the bone marrow, where the initial stages of maturation occur, and travel to the spleen for final steps of maturation into naïve mature B cells.
1108260
also known as B lymphocytes, are specialized lymphocytes that produce and secrete antibodies. Each lymphocyte makes a specific antibody that is capable of destroying a specific antigen. are specialized white blood cells that patrol the body the body searching for antigens that produce infections.
166492
B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell. Once released into the blood and lymph, these antibody molecules bind to the target antigen (foreign substance) and initiate its neutralization or destruction.

Plasma cells, also called plasma B cells, are white blood cells that originate in the bone marrow and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.
837525
There are two types of B cells: Plasma B cells secrete antibodies which effect the destruction of antigens by binding to them and making them easier targets for phagocytes.
