Streptavidin-Coated Magnetic Beads

Magnetic beads with covalently linked streptavidin are commonly used for assays to detect or immobilise biotinylated biomolecules. We offer streptavidin-coated beads with different properties.

Especially our MagSi-STA 600 BI beads with streptavidin-coated surface are perfectly suited for any kind of pull-out/pull-down-assay for RNA/DNA, or proteins. These beads are characterised by

  • Small size and dense loading with a modified streptavidin
  • Extremely high binding capacity for biotin (6800 pmol biotin/mg beads)
  • Low unspecific binding
  • High yield and sample purity

Depletion of ribosomal RNA for RNA-Seq

A highly efficient alternative to RiboZero from Illumina

Due to their enormous binding capacity for biotinylated target molecules, our MagSi-STA 600BI beads are perfectly suited for rRNA-Depletion (in combination with biontinylated oligos like the riboPOOLs from siTools Biotech). Because of their low unspecific binding of mRNA our beads provide a significantly higher yield of mRNA than beads from other suppliers.

MagSi-STA TRIAL Kit

MagSi-STA Trial Kit

Our TRIAL Kit is a perfect tool to find out which beads are best suited for your application. It consists of 1 mL each of  8 different MagSi-STA beads (bead sizes 600 nm, 1 µm, 3 µm, each as hydrophobic and hydrophilic version, and the 1 µm beads with two different binding capacities). By testing all versions parallel with your sample, you will quickly identify the ideal bead version for your application.
