Molday LION™ Family of Products
Molday LION™ and Molday LION™ Rhodamine B are ultrasmall mixed ferrite iron oxide-based superparamagnetic contrast agents having a colloidal size of approximately 35 nm. The core crystal is europium-doped magnetite surrounded by a cross-linked dextran to which a fluorescent dye, such as rhodamine B, can be attached. Thess agents can be visualized by MRI, fluorescence (if a dye is present) and quantified by neutron activation (via BioPAL's short enhanced assay service). For fluorescence, the rhodamine B label excitation wavelengh is 555 nm and the emission is 565-620 nm. Molday LION can be supplied with alternative fluorescent dyes. Please inquire.
