Streptavidin-ZAP [IT-27, KIT-27-A, KIT-27-B, KIT-27-Z]

a tool to “piggyback” onto YOUR biotinylated material via streptavidin; targeting cells that recognize YOUR biotinylated material, eliminated via saporin

SKU: IT-27 Category: Conjugate: saporin | Usage: converts biotinylated materials, eliminates cells |

Streptavidin-ZAP converts biotinylated materials into targeted toxins. Streptavidin is a tetrameric protein (molecular weight 53 kDa in its recombinant form), with each subunit able to bind a single biotin molecule. The bond between streptavidin and biotin is rapid and essentially non-reversible, unaffected by most extremes of pH, organic solvents, and denaturing reagents. It is the strongest known noncovalent biological interaction (Ka = 1015 M-1) between protein and ligand. The streptavidin used to make Streptavidin-ZAP contains no carbohydrate group and has a neutral isoelectric point, which therefore reduces the nonspecific binding as compared to avidin. A variety of molecules, including lectins, proteins, and antibodies, can be biotinylated and reacted with streptavidin-labeled probes or other detection reagents for use in biological assays.

Streptavidin-ZAP is a chemical conjugate of streptavidin and the ribosome-inactivating protein, saporin. It converts biotinylated materials into targeted toxins.

Streptavidin-ZAP is available individually (Cat. #IT-27) and in multiple kit variations.
