particulate antigen
1antigen — Any substance that, as a result of coming in contact with appropriate cells, induces a state of sensitivity and/or immune responsiveness after a latent period (days to weeks) and that reacts in a demonstrable way with antibodies and/or immune… …
2agglutinin — 1. An antibody that causes clumping or agglutination of the bacteria or other cells that either stimulated the formation of the a., or contain immunologically similar, reactive antigen. SYN: agglutinating antibody, immune a.. 2. A substance,… …
3agglutinogen — An antigenic substance that stimulates the formation of specific agglutinin, which can cause agglutination of cells that contain the antigen or particles coated with the antigen. SYN: agglutogen. [agglutinin + G. gen, production] …
