NucleoTrap® NucleoTrap® mRNA
Technology /
separation principle
Silica-matrix technology /
chaotropic salt binding
Affinity chromatography
Material Spherical silica beads Oligo(dT) latex beads
Format Silica bead suspension Latex bead suspension – NucleoTrap®
Microfilters for bead separation
Procedure Principle: binding (high-salt) –
washing – elution (low-salt)

• Adsorption of DNA / RNA 
   in the presence of chaotropic 
   salts (hydrate shell of DNA/RNA 
   is reversibly removed)
• High-salt / ethanolic washing
   steps to remove contaminants
• Low-salt or water elution
  (hydrate shell is recovered,
  DNA / RNA is released from the
Principle: binding (high-salt) –
washing – elution (low-salt)

• Hybridization of poly(A) mRNA on
  oligo(dT) latex beads under
