The clumping of antigens with antibodies or of the red blood cells from one type of blood with the red blood cells of another type. A clumping together of cells. The act of coming together or sticking to one another to form a clump, as of bacteria cells in the presence of serum, or blood…

A protein substance, such as an antibody, that is capable of causing agglutination (clumping) of a particular antigen. Antibodies that function with homologous antigens to form lumping or agglutination. A factor in a serum which makes cells stick together in clumps. Antibodies demonstrated by their ability to agglutinate their corresponding antigen. Where the antigen is…

Lack of milk after parturition (birth). Failure of the mother to secrete enough milk to feed a suckling infant. Absence of milk or milk flow. A condition in which a mother is unable to produce milk after childbirth. Condition in which milk is not secreted or is not contained in a mother’s breasts after she…

An inherited disorder in which there are very low levels of protective immune proteins called immunoglobulins. Cf. x-linked agammaglobulinaemia. A deficiency or absence of immunoglobulins in the blood, which results in a reduced ability to provide immune responses.

Resultant products of a chain of chemical reactions after an initial glycation reaction. AGEs may play an important adverse role in process of atherosclerosis, diabetes, aging and chronic renal failure.
