Neutravidin-functionalized silica magnetic beads
eMAG Si-cN magnetic beads are 2.5 µm silica magnetic beads functionalized with NeutravidinTM for the capture of biotinylated molecules or biotinylated antibodies. Quality controls are performed to ensure the maximum quality of our product. We perform three main controls in the production pipeline: (i) test of size distribution, (ii) test of paramagnetic activity and (iii) test of the density of functionalization. The density of functionalization of eMAG Si-cN is certified by the labeling of fluorescent biotinylated molecules (Figure 1). The binding capacity calculated using Biotin-ATTO647N is 15 nmol biotinylated molecules/ml beads.
