screenMAG screenMAG-particles are magnetic-fluorescent beads based on the well-known SiMAG technology. The advantage of both innovative techniques - the magnetic- and the fluorescence properties - provide exciting new possibilities to explore new fields of application in biosciences.   FluorescenceType FluorescenceColor Excitation Emission screenMAG/B blue 400 nm 420 nm screenMAG/G green 502 nm 525 nm screenMAG/O orange 526 nm 555 nm screenMAG/OP orange 536 nm 617 nm screenMAG/RR red 540 nm 625 nm screenMAG/R red 633 nm 672 nm Fluorescence image of screenMAG/G particles under magnetic field Fluorescence image of screenMAG/O particles under magnetic field   NOTE: The fluorescence of the screenMAG particles is only detectable on the same side where the excitation takes place. Please note that there is a difference in fluorescence observation between dissolved fluorescence molecules and solid fluorescence particles. Fluorescence spectrophotometer with a fluorescence detection unit with an angle of 90° to the excitation source will detect no or only weak fluorescence signals. screenMAG-active screenMAG-active - terminal reactive groups of the magnetic-fluorescent beads allow the convenient and efficient covalent binding of bioaffine ligands. This is a unique feature accounting for the rapidly increasing number and variation of novel and different receptor-affine biological substances.
