| agglutinin | 1. An antibody that causes clumping or agglutination of the bacteria or other cells which either stimulated the formation of the agglutinin, or contain immunologically similar, reactive antigen. Synonym: agglutinating antibody, immune agglutinin. 2. A substance, other than a specific agglutinating antibody, that causes organic particles to agglutinate, commonly qualified, e.g., plant agglutinin. (05 Mar 2000) |
|---|---|
| major agglutinin | Immune agglutinin present in greatest quantity in an antiserum and evoked by the most dominant of a mosaic of antigens. Synonym: chief agglutinin. (05 Mar 2000) |
| partial agglutinin | Immune agglutinin present in an antiserum in lesser concentration than the major agglutinin. Synonym: partial agglutinin. (05 Mar 2000) |
| peanut agglutinin | <protein> Lectin from Arachis hypogaea that binds to glycoproteins containing _ D gal (1_3) D galNAc in membranes, used to investigate differential adhesiveness in developing systems. (18 Nov 1997) |
| chief agglutinin | Immune agglutinin present in greatest quantity in an antiserum and evoked by the most dominant of a mosaic of antigens. Synonym: chief agglutinin. (05 Mar 2000) |
| Ricinus communis agglutinin | <protein> Lectin (120 kD) from castor bean, with specificity similar to ricin, but much less toxic. (18 Nov 1997) |
| group agglutinin | An immune agglutinin specific for a group antigen. Synonym: cross-reacting agglutinin. (05 Mar 2000) |
| minor agglutinin | Immune agglutinin present in an antiserum in lesser concentration than the major agglutinin. Synonym: partial agglutinin. (05 Mar 2000) |
| cold agglutinin | An antibody which reacts more efficiently at temperatures below 37캜. (05 Mar 2000) |
| wheat germ agglutinin | <plant biology> Lectin from wheat germ that binds to N acetylglucosaminyl and sialic acid residues. See: lectins. (18 Nov 1997) |
| wheat germ agglutinin-horseradish peroxidase conjugate | <chemical> The lectin wheatgerm agglutinin conjugated to the enzyme horseradish peroxidase. It is widely used for tracing neural pathways. Pharmacological action: molecular probes. (12 Dec 1998) |
| cross-reacting agglutinin | An immune agglutinin specific for a group antigen. Synonym: cross-reacting agglutinin. (05 Mar 2000) |
| H agglutinin | An agglutinin 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. Synonym: flagellar agglutinin. See ABO blood group. (05 Mar 2000) |
| saline agglutinin | An antibody which causes agglutination of erythrocytes when they are suspended either in saline or in a protein medium. (05 Mar 2000) |
| serum agglutinin | 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. Synonym: incomplete antibody. (05 Mar 2000) |
