what does agglutination mean in chemistry?
16977
Agglutination is the clumping of particles. The word agglutination comes from the Latin agglutinare (glueing to). Agglutination is the process that occurs if an antigen is mixed with its corresponding antibody called isoagglutinin.

the clumping together in suspension of antigen-bearing cells, microorganisms, or particles in the presence of specific antibodies (agglutinins).

Definition. Agglutination is the process of clumping of antigens with their respective antibodies. Precipitation is a process where soluble antigens bind with their specific antibody at an optimum temperature and pH, resulting in the formation of an insoluble precipitate. Antigen size.

Chegg.com. Agglutination is a type of serological reaction used to determine antigen-antibody reaction. Agglutination reaction involves clumping together of antigens like bacterial cell, red blood cells, animal cells and others with specific antibodies, leading to crosslinking and thus formation of lattice structure.

An antibody (formally called immunoglobulin) is a large Y-shaped glycoprotein produced by B-cells and used by the immune system to identify and neutralize pathogens. Antibodies are produced by B cells, and are either secreted into circulation or remain expressed on the surface of the B cell.

Antibody, also called immunoglobulin, a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body.

Febrile Antigen Direct Test. INTENOED USE CENOGENICS' FEBRILE ANTIGENS (bacterial agglutination antigens) are bacterial suspensions for use in either slide or tube agglutination tests to detect the presence of bacterial agglutinins associated with bacterial infection or previous exposure to a related organism.

Passive Agglutination Is Useful with Soluble Antigens. ... Whether based on red blood cells or the more convenient and versatile synthetic beads, agglutination reactions are simple to perform, do not require expensive equipment, and can detect small amounts of antibody (concentrations as low as nanograms per milliliter).

Both reactions are highly specific because they depend on the specific antibody and antigen pair. The main difference between these two reactions is the size of antigens. For precipitation, antigens are soluble molecules, and for agglutination, antigens are large, easily sedimented particles.

Agglutinogen B are present on the RBC. An agglutinogen is an antigen and a agglutinin is generated by the body within the immune system as a result of the agglutinogen. 2.

Agglutination is the clumping of particles. ... When people are given blood transfusions of the wrong blood group, the antibodies react with the incorrectly transfused blood group and as a result, the erythrocytes clump up and stick together causing them to agglutinate.

neutralization: The reaction between an acid and a base in which neutral water is produced. titration: A laboratory technique that very accurately measures the concentration of a solution of an acid or a base.

Antigen is a molecule capable of causing the immune system to produce antibodies against it. It may be foreign or formed inside the body. Antigens are usually polysaccharides , lipids or peptides e.g. hemagglutinin ( found in Influenza virus ) . Pathogen is an infectious agent that may cause a disease.

In blood typing, antigens on the surfaces of red blood cells (RBCs) are also known as agglutinogens and the antibodies that react against them are also called agglutinins. Antibodies in the blood are found in the plasma.

Medical Definition of autoagglutination : agglutination of red blood cells by cold agglutinins in an individual's own serum usually at lower than body temperature.

Green AHG is made by adding erioglaucine and naphthol yellow S to the blend. The test procedure is based on the agglutination principle, where human immunoglobulins and/or complement attached to the red cell surface agglutinates in the presence of the polyspecific AHG indicating a positive result.

Both agglutination and coagulation refer to the massing of small particles in a suspension. ... The main difference between agglutination and coagulation is that agglutination refers to small particles coming together whereas coagulation refers to the formation of a clump.
