The FeraTrack™ MRI Contrast Agent Kit is an optimal ready-to-use solution for cell tracking in vivo using pre-clinical MRI. Our newly developed FeraTrack Contrast Particles are superparamagnetic iron oxide (SPIO) particles specifically formulated for ex vivo labeling of various cell types prior to transplantation and pre-clinical MRI. Once within cells, SPIOs can induce decreased signal intensity on T1-, T2-, and T2*-weighted images. The FeraTrack Labeling Kit was optimized for proper in vitro labeling of cell lines (NIH-3T3, Jurkat), primary cells (granulocytes, neural progenitors), and stem cells (hematopoietic, mesenchymal, and embryonic stem cells) from different species (mouse, human, rat).
