The antibody recognizes a unique molecule of the pathogen, called an antigen . (wikipedia.org)
[2] [3] Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. (wikipedia.org)
To allow the immune system to recognize millions of different antigens, the antigen-binding sites at both tips of the antibody come in an equally wide variety. (wikipedia.org)
The class hence determines the function triggered by an antibody after binding to an antigen, in addition to some structural features. (wikipedia.org)
After an antigen binds to a BCR, the B cell activates to proliferate and differentiate into either plasma cells , which secrete soluble antibodies with the same paratope, or memory B cells , which survive in the body to enable long-lasting immunity to the antigen. (wikipedia.org)
Structurally an antibody is also partitioned into two antigen-binding fragments (Fab), containing one V L , V H , C L , and C H 1 domain each, as well as the crystallisable fragment (Fc), forming the trunk of the Y shape. (wikipedia.org)
