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.

| screenMAG/O | orange | 526 nm | 555 nm |
| screenMAG/OP | orange | 536 nm | 617 nm |

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 - 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.
