Revvity IVISense Transferrin Receptor 750 Fluorescent Probe (Transferrin-Vivo)

IVISense Transferrin Receptor 750 is a targeted fluorescent imaging probe, where recombinant transferrin is conjugated to an IVISense fluorescent dye, designed to bind to transferrin receptors (TfRs) expressed in cancer cells. Because of rapid cell division and stringent demand for iron (for heme synthesis), many cancer cell types overexpress TfRs. It has been used as a targeting agent for cancer cells. In addition, TfR accumulates in locals of inflammation due to the leakage of plasma proteins and to the expression of TfR receptors by inflammatory cells. During inflammation monocytes leave the blood and differentiate into macrophages at the extravascular tissues, macrophages express surface Tf receptors.
