 (fragment, antigen-binding)
originally, either of two identical fragments, each containing an antigen combining site, obtained by papain cleavage of the IgG molecule; now generally used as an adjective in terms such as Fab fragment or region, referring to an “arm” of any immunoglobulin monomer, i.e., one light chain and the adjoining heavy chain VH and CH1 domains.
digoxin immune Fab (ovine) a preparation of antigen-binding fragments derived from specific antidigoxin antibodies produced in sheep that have been immunized with digoxin coupled as a hapten to human serum albumin, used as an antidote to life-threatening digoxin and digitoxin overdose; administered intravenously.
