A substance inducing and reacting in an immune response. Normally antigens have molecular weights greater than about 1 kD. The antigenic determinant group is termed an epitope and the association of this with a carrier molecule (that may be part of the same molecule) makes it active as an antigen. Thus dinitrophenol-modified human serum albumin is antigenic to humans, dinitrophenol being the hapten. Usually antigens are foreign to the animal in w â€¦
