Daniels TR, Ng PP, Delgado T, Lynch MR, Schiller G, Helguera G, Penichet ML (2007) Conjugation of an anti transferrin receptor IgG3-avidin fusion protein with biotinylated saporin results in significant enhancement of its cytotoxicity against malignant hematopoietic cells. Mol Cancer Ther 6:2995-3008. doi: 10.1158/1535-7163.MCT-07-0330

Summary: The human transferrin receptor (hTfR) is overexpressed in malignant cells. Using Advanced Targeting System’s custom biotinylation service, the authors combined an anti-hTfR antibody-avidin fusion protein with biotinylated saporin (Cat. #PR-01, saporin alone), and examined the effect of the combined complex on cancer cells in vitro. Although the antibody-avidin fusion protein has an intrinsic cytotoxic effect, the fusion protein-saporin complex was able to eliminate the population of cells that showed resistance to the fusion protein alone.
