agglutinin

agglutinin (a-glu´ti-nin)

1. An antibody that causes clumping or agglutination of the bacteria or other cells which either stimulated the formation of the a., or contain immunologically similar, reactive antigen.agglutinating antibody, immune a; 2. A substance, other than a specific agglutinating antibody, that causes organic particles to agglutinate, commonly qualified, e.g., plant a.
blood group a.'s see Blood Groups appendix.
chief a. major a
cold a. an antibody which reacts more efficiently at temperatures below 37°C.
cross-reacting a. group a
flagellar a. H a. (1)
group a. an immune a. specific for a group antigen.cross-reacting a;
H a. 1. an a. that is formed as the result of stimulation by, and which reacts with, the thermolabile antigen(s) in the flagella of motile strains of microorganisms;flagellar a; 2. see ABO blood group, Blood Groups appendix.
immune a. agglutinin (1)
incomplete a. (a-glu´ti-nin) antibody that binds to antigen but does not induce agglutination. These antibodies are usually of the IgG class and are referred to as incomplete antibody.
major a. immune a. present in greatest quantity in an antiserum and evoked by the most dominant of a mosaic of antigens.chief a;
minor a. immune a. present in an antiserum in lesser concentration than the major a.partial a;
O a. 1. an a. that is formed as the result of stimulation by, and that reacts with, the relatively thermostable antigen(s) in the cell bodies of microorganisms;somatic a; 2. see ABO blood group, Blood Groups appendix.
partial a. minor a
plant a. a lectin.
saline a. an antibody which causes agglutination of erythrocytes when they are suspended either in saline or in a protein medium.complete antibody;
serum a. an antibody which coats erythrocytes; the cells do not agglutinate when suspended in saline, but do agglutinate when suspended in serum or other protein media such as albumin.incomplete antibody (2);
somatic a. O a. (1)
