Bio-Estapor® Streptavidin Magnetic Microspheres
The protein streptavidin, due to high COOH group surface density, is covalently attached to the Bio-Estapor® Streptavidin magnetic microspheres. For this reason, our streptavidine-coated microspheres can be regenerated and reused for the same application with no significant loss of yield.
Estapor's new proprietary polymerisation technology (patent pending) has recently created a new line of COOH microspheres from 0.15 µm to 3.0 µm. We have selected five different sizes of microspheres to better cover all the applications using streptavidin-coated beads.
Characteristics of Bio-Estapor® Streptavidin Magnetic Microspheres
- High surface area
- High content of ferrite
- High level of COOH groups
- Low non-specific-binding
