SeraSil-Mag 700 beads 5 mL silica coated superparamagnetic beads
High magnetization (60emu/g) and strong binding capacity giving fast magnetic response (~5 secs) and shorten time required for magnetic steps during isolation.
Beads are monodispersed with narrow size distribution for consistent, reproducible results.
Silanol hydroxyl groups on the bead surface give efficient, high purity isolation of nucleic acids.
Tested for microbial contamination.
Good buoyancy stability (low sedimentation rate): beads remain well suspended and dispersed for over 90 mins (at 1 mg/ml concentration),* providing good handling and suitability for automation.
*Beads may settle faster at higher concentration
Beads come in two sizes (submicroscale diameter ~700 nm and 400 nm), offering choice based on surface requirements.
SeraSilMag silica beads exhibit high magnetization in the presence of a magnetic field (superparamagnetic) and have a fast magnetic response rate. At the same time, they provide good buoyancy stability, with beads remaining wellsuspended and dispersed after standing for >90 mins. SeraSilMag beads are compatible with chaotropic salt chemistry and vortex mixing, roller mixing and sonication.
Tightly controlled production processes result in coreshell beads which are uniform and spherical. The silica shell provides a high content of silanol surface groups and encloses the magnetic core. The submicron size allows for a high surface area and abundant binding sites. The narrow particle size distribution assures uniformity and consistency of the beads.
The magnetic nanoparticles within the core provide superparamagnetic properties to the SeraSilMag beads, resulting in extremely fast magnetic separation in the presence of a magnet. There is no residual magnetization when the magnetic field is removed, which further contributes to ease of handling during use.
