Datasheet Magnetic Beads Bioconjugation

Absolute Mag™ Plain Magnetic Nanoparticles, Cross-linked Dextran Matrix, Fluorescent Far Red, 70 nm (#WHM-M109) are synthesized as a flower-shaped iron oxides in a matrix of crosslinked dextran. These magnetic particles, with far red fluorescence (excitation: 732 nm, emission: 758 nm), are excellent tracers for Magnetic Particle Imaging (MPI) and cannot be separated with a conventional permanent magnet but in a high gradient magnetic field. Polydispersity index: < 0.2.
