Rab-ZAP uses your primary rabbit affinity-purified polyclonal IgG antibody to target and eliminate cells that recognize your primary antibody. This secondary conjugate uses the secondary antibody (affinity-purified goat anti-rabbit IgG) to “piggyback” onto YOUR rabbit primary antibody. Rab-ZAP can be utilized for screening rabbit IgG antibodies for internalization and/or their suitability to make potent immunotoxins.
Rab-ZAP is a chemical conjugate of affinity-purified goat anti-rabbit IgG and the ribosome-inactivating protein, saporin. It uses your rabbit affinity-purified polyclonal antibody to target and eliminate cells. This secondary conjugate is used to evaluate the potential of a primary antibody to internalize.
Rab-ZAP is available individually (Cat. #IT-05) or as a kit (Cat. #KIT-05) which includes Rab-ZAP, Saporin (Cat. #PR-01), Goat IgG-SAP (Cat. #IT-19) and reagents for developing a cytotoxicity assay.

Evaluate Potential Targeting Molecules.
Kohls M (2006) Evaluate Potential Targeting Molecules. Nature Methods
Summary: Targeted toxins -- targeting agents conjugated to saporin -- are widely used to eliminate specific cell populations both in vitro and in vivo. For these molecules to be effective, it is vital that the targeting component of the conjugate specifically binds the cells of interest. A secondary conjugate, Streptavidin-ZAP, has been created by attaching the toxin saporin to streptavidin. The user can combine primary biotinylated material with Streptavidin-ZAP to quickly and economically screen potential targeting molecules for internalization and specificity. Once the appropriate targeting molecule is identified, a direct conjugation with saporin can be performed.
