Immobilon®-PSQ PVDF membrane for Western blotting

Immobilon®-PSQ transfer membrane for smaller proteins. This PVDF membrane has a 0.2 μm pore size with a thickness of ~200 μm. Because it has smaller pores and approximately three times the internal surface area of most membranes, Immobilon®-PSQ membranes have higher protein binding capacity, improving retention of small proteins. Ideal for Westerns involving lysates or small proteins (<20 kDa) and challenging Westerns due to low-abundance target proteins, low-affinity antibodies.

Key Benefits

  • Higher binding capacity and retention resulting in stronger signals
  • Prevents blow-through of low molecular weight proteins (<20 kDa)
  • Compatible with chemiluminescent and fluorescence detection techniques
