Digoxin Immune Fab (Ovine)

Digibind, digoxin immune Fab (ovine), is a sterile lyophilized powder of antigen binding fragments (Fab) derived from specific antidigoxin antibodies raised in sheep. Production of antibodies specific for digoxin involves conjugation of digoxin as a hapten to human albumin. Sheep are immunized with this material to produce antibodies specific for the antigenic determinants of the digoxin molecu...

Fab-arm exchange

636 mAbs Volume 4 issue 6 Immunology and structural biology are highly complex fields of study in which mechanisms and inter-relationships are often not easily understood. It is therefore quite common to use metaphors to make knowledge gained accessible to experts and non-experts alike. Thus we, for example, all know the antibody as a Y-shaped protein with two arms and a tail and we understand ...

Structure of the omalizumab Fab.

Omalizumab is a humanized anti-IgE antibody that inhibits the binding of IgE to its receptors on mast cells and basophils, thus blocking the IgE-mediated release of inflammatory mediators from these cells. Omalizumab binds to the Fc domains of IgE in proximity to the binding site of the high-affinity IgE receptor FcℇRI, but the epitope and the mechanisms and conformations governing the recognit...
