| Characteristics | Advantages |
| Streptavidin coverage is optimized | Binding capacity is improved |
| Streptavidin is covalently coupled | Reagent is more stable |
| Estapor® microspheres are perfectly uniform | Non specific binding is really reduced |
| Estapor® microspheres are perfectly spherical | Aggregation problems are lower |
| Estapor® microspheres are encapsulated | Biomolecules are protected from iron |
| Estapor® microspheres have a 1µm size | Surface area and reactivity are higher |
| Estapor® microspheres are super paramagnetic | After attraction beads re-suspension is easier |
| Estapor® microspheres contain 40% of ferrite | Magnetic attraction is very fast |
