Absolute Mag™ Protein A Magnetic Particles, Smooth Surface, 3.0-3.9 μm (# WHM-S085) have a thick layer of polymer coating with covalently coupled Protein A on the surface of the particles. There is no exposed iron oxide on the surface of the particles. They are used in nucleic acid isolation, protein purification, immunology, and cell separations, especially used for the immunomagnetic separation (IMS) and real-time PCR to detect Escherichia coli. Otherwise, they are available impregnated with fluorophores for flow cytometry or easy bead location identification in phagocytosis assays.
|Q: What's the binding capacity of these particles?|
|A: 4.27 ug of Human-FITC to 1 mg of particle; 4.37 ug of Rabbit-FITC to 1 mg of particle; 2.95 ug of Mouse-FITC to 1 mg of particle.|
