Antibodies are gamma globulin proteins that are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses. They are...

If the appropriate antibodies are present in the body, they combine with the capsule. Coated with protein instead of polysaccharide, the pneumococci are now easy to ingest.
These photomicrographs show phagocytosis of antibody-coated pneumococci.
Monoclonal antibodies can be grown in unlimited quantities in the bottles shown in this picture.
Antibodies specific for the different neoepitopes generated by such cleavage events provide powerful tools with which to analyse these processes.
Antibodies
Antibodies bind to specific antigens in a lock-and-key fashion, forming an antigen-antibody complex. Antibodies are a type of protein molecule known as immunoglobulins.
antibodies Proteins produced by immune system cells that bind to foreign molecules and microorganisms and inactivate them. PICTURE ...
Antibodies are immune system-related proteins called immunoglobulins. Each antibody consists of four polypeptides- two heavy chains and two light chains joined to form a "Y" shaped molecule.
Antibodies help the body develop immunity to disease. Blood proteins are produced in response to a disease and help the body fight against the particular disease. [Talking Glossary]

6.5 Antibodies and bacteria.
Illustrates the attachment of antibodies onto bacteria. Antibodies help "butter" them up for white blood cells to eat.
6.6 Viral infection and release.
The use of antibodies or antisera as histological tools for identifying patterns of antigen distribution within a tissue or an organism.
Monoclonal antibodies took about 20 years from the time they first came on the scene to actually deliver us really wonderful, useful products- such as for treating autoimmune disease.

Catalytic antibodies Antibodies generated by using transition-state analogs of a particular reaction as antigens. Such antibodies often function as catalysts for the reaction. Also called abzymes.
Monoclonal antibodies. Immunoglobulin molecules of single- epitope specificity that are secreted by a clone of B cells.
Monoculture. The agricultural practice of cultivating crops consisting of genetically similar organisms.
The selection of antibodies (single chain Fvs - scFvs) against protein targets can be done using a number of different systems, including phage, phagemid, bacterial or yeast display vectors.

Others are antibodies, the molecules that are made by special white blood cells (lymphocytes) to fight off foreign organisms and molecules. Antibodies are proteins that contain four polypeptide chains.

The extensive intertwined network was labeled with primary antibodies to several cytokeratin proteins, which were then stained with secondary antibodies containing a green fluorescent dye.
The structure of the antibody consists of two light chains and two heavy chains, and at the very tip of the antibody is a hypervariable region, and this hypervariable region allows the antibody to make different types of antibodies that will respond ...
The pigments are chemically bonded to antibodies, which are then put into a solution of cells.
- A type of cell that produces antibodies.
Bacillus thuringiensis
- A naturally occurring bacterium with pesticidal properties. Bacillus thuringiensis produces a protein (Bt toxin) that is toxic only to certain insect larvae that consume it.
A library of proteins (e.g., peptides, antibodies, purified proteins, or unknown protein samples) is spotted on microscopic slides. They are usually used to identify novel proteins or protein-protein interactions.

That artificial construct (the "expression clone") will produce a pseudo-mammalian protein if put back into bacteria. Often, that protein can be recognized by antibodies raised against the authentic mammalian protein, and vice versa.
Not only do your nodes remove cells, they also create cells called lymphocytes. Those lymphocytes are white blood cells used by the immune system to produce antibodies or hunt down pathogens and eat them (using phagocytosis).
