Immobilon®-PSQ Membrane

Request Information

---

This membrane has higher protein adsorption and sequencing yields than other membranes.

• 0.2 µm pore size and a large internal structure
• Higher protein adsorption and sequencing yields than other membranes
• Recommended for blotting proteins <20 kDa
• Prevents blow-through of low molecular weight proteins

Immobilon®-P^SQ membrane prevents blow-through.

Molecular weight standards (lanes 1, 3, 5, 7) and calf liver lysate (lanes 2, 4, 6, 8) were transferred to Immobilon®-P or Immobilon®-P^SQ membranes. A sheet of Immobilon®-P^SQ transfer membrane was placed behind the primary membranes to capture proteins that passed through (lanes 5 and 6 behind Immobilon®-P; lanes 7 and 8 behind Immobilon®-P^SQmembrane).
