Super-Paramagnetic Iron Oxide Tracer

For Preclinical Magnetic Resonance and Magnetic Particle Imaging (MPI)

VivoTrax is used for MRI and MPI research for cell tracking, vascular imaging, and lymph node imaging.

VivoTrax is one of the few available tracers proven on magnetic particle imaging due to their unique magnetic properties. Certain dextran magnetites are not only used for cell tracking, but approved for clinical imaging in many countries to detect liver carcinomas.

VivoTrax & VivoTraxPlus™ is available in 5-tube packages. Each vial contains 1.1 mL of VivoTrax superparamagnetic iron oxide (SPIO) dextran magnetite nanoparticle solution, comprising ~5.5 mg/mL total iron and ~6 mg/mL carboxydextran in sterilized PBS Endotoxins <0.5 EU/mg Fe.
