Agglutination, which refers to the clumping of particles together, is an antigen-antibody reaction that occurs when an antigen (i.e., a molecule capable of triggering the adaptive immune response) is mixed with its corresponding antibody at a suitable pH and temperature.
Agglutination is a reaction in which particles (as red blood cells or bacteria) suspended in a liquid collect into clumps usually as a response to a specific antibody. Agglutination (clumping) of red blood cells. This occurs in biology in two main examples:
Agglutination is an antigen-antibody reaction in which a particulate antigen combines with its antibody in the presence of electrolytes at a specified temperature and pH resulting in the formation of visible clumping of particles.
Agglutination is a biological process in which particles, such as cells or microorganisms, clump together in the presence of specific antibodies. This phenomenon occurs when antibodies bind to antigens present on the surface of these particles, causing them to stick together and form visible aggregates or clumps. Table of Contents.
Agglutination is a process that ends in the formation of a clump. In coagulation, the process entails a more complex process such that a platelet plug forms initially, and then is subsequently reinforced with a fibrin clot.
: a reaction in which particles (such as red blood cells or bacteria) suspended in a liquid collect into clumps and which occurs especially as a serologic response to a specific antibody. Examples of agglutination in a Sentence.
Agglutination reaction can define as the serological reaction where the large or particulate antigen is mixed with the antiserum containing antibodies in solid support like glass side, microtitre plate or test tubes.
Agglutination is the visible expression of the aggregation of antigens and antibodies. Agglutination reactions apply to particulate test antigens that have been conjugated to a carrier. The carrier could be artificial (such as latex or charcoal particles) or biological (such as red blood cells).
Learning Objectives. Compare direct and indirect agglutination. Identify various uses of hemagglutination in the diagnosis of disease. Explain how blood types are determined. Explain the steps used to cross-match blood to be used in a transfusion.
Agglutination is a specific reaction, i.e. a particular antigen will only clump in the presence of its specific antibody; it therefore provides a means of identifying unknown bacteria and determining blood group.
