F (ab')2, Fab, Fab' and Fv are antigen-binding fragments that can be generated from the variable region of IgG and IgM. These antigen-binding fragments vary in size (MW), valency and Fc content. Fc fragments are generated entirely from the heavy chain constant region of an immunoglobulin. WebAntigens are classified as exogenous (entering from outside) endogenous (generated within cells ), an autoantigen, a tumor antigen, or a native antigen. Antigenic specificity is the ability of host cells to recognize an antigen by its unique molecular structure, such as the relationship between antigen epitopes and antibody paratopes. dr buis chiropractor hawthorne nj
