Rabishield-100 (Rabies Human Monoclonal Antibody)

Rabishield is a sterile solution of fully human IgG1 monoclonal antibody specific to the rabies virus surface G glycoprotein for local infiltration in the wounds and intramuscular administration following a suspected rabies exposure. It must be used in combination with a commercially available rabies vaccine and injected at sites distant from the rabies vaccine administration for post exposure prophylaxis. The product is standardized against the National and International Reference Standard Rabies Immune Globulin. 

The fully human monoclonal antibody was originally isolated from hybridomas derived from transgenic mice with human immunoglobulin genes immunized with inactivated rabies vaccine. Rabishield is produced by recombinant DNA technology using CHO-K1 cells and purified. Rabishield binds to a conformational epitope of the ectodomain at antigenic site III anminor site a of the rabies G glycoprotein. Binding of Rabishield to the G glycoprotein probably prevents viral attachment to target cells. Rabishield neutralizes a wide variety of terrestrial and bat isolates of rabies virus tested by a standardized rapid fluorescence focus inhibition test (RFFIT).
