Targeting Tools: Oxytocin-SAP

Oxytocin-SAP (Cat. #IT-46) is a conjugate (molecular weight 31 kDa) between the native oxytocin peptide and saporin. Oxytocin is a nine amino acid peptide with a structure similar to vasopressin, and is a hormone released by the posterior pituitary. Peripheral activity of oxytocin is linked primarily to lactation and labor-related uterine contractions. Within the brain, …

Targeting Tools: Anti-Basigin

This mouse monoclonal antibody (Cat. #AB-42; Clone P2C2) recognizes human Basigin. The antibody is purified by ammonium sulfate precipitation on conditioned medium and then further purified through Protein-A. The antibody is routinely tested by flow cytometry. The immunoglobulin superfamily protein basigin (EMMPRIN/CD147) is a cell surface glycoprotein expressed by tumor cells that stimulates matrix metalloproteinase …

Targeting Tools: Bombesin-SAP

Bombesin-SAP (Cat. #IT-40) specifically targets and eliminates gastrin- releasing peptide receptor (GRPR)-positive cells. This targeted toxin (molecular weight 31.8 kDa) is a chemical conjugate of bombesin and the ribosome-inactivating protein, saporin. Please see cover article (pp. 1, 6) for an example of its experimental use.
