Molday ION Rhodamine B (MIRB)

Technical Information

Molday ION™ Rhodamine B is without question the best cell labeling and MRI tracking reagent on the market today.

Molday ION Rhodamine B (MIRB) is an iron oxide-based superparamagnetic MRI contrast reagent (USPIO) having a colloidal size of 35 nm. This colloid is specifically designed for cell labeling and MRI tracking and does not require transfection reagents for efficient cell labeling. This USPIO is cross-linked for stability and labeled with the fluorescent dyes Rhodamine B. Molday ION Rhodamine B can be visualized by both MRI (T2 imaging agents) and fluorescence. Using magnetic fields, labeled cells can be magnetically held to enhance cellular grafting.

All cell-types can be successfully labeled with MIRB, including Adherent cells, Suspension Cells, Stem Cells, Primary Cells, T-Cels, and even platelets.

If you are looking for an easy-to-use, fool-proof procedural method to label and than track cells by MRI and fluorescence imaging, we strongly recommend that you give MIRB a try!


Stem cell labeling imaging and tracking via MRI and magnetic retention for stem cells.
