A microporous polyvinylidene difluoride membrane, PolyScreen is an effective alternative to nitrocellulose membranes for protein transfers.

  • Sensitive: detects low levels of protein and decreases exposure times
  • Easy to use: adapts to most nitrocellulose membrane protocols with the addition of a pre-wetting step
  • Durable: stronger than nitrocellulose, it won’t tear, crack or shrink, so there are no rips or crackles on your autorads and your molecular weight markers are not distorted
  • Reprobable: retains more protein than nitrocellulose, even during the most stringent washes
  • Flexible: for use with standard blocking reagents (nonfat dry milk, casein, non-ionic surfactants or BSA) and all common immunostains, chromogenic and chemiluminescent substrates
  • Wettable: entire membrane is prepared consistently, so transfers are more efficient
  • Archivable: won’t shatter when dry, or discolor over time
  • Safe: nonflammable, requires no special handling, storage or shipping precautions
  • Versatile: can be used for protein staining (compatible with commonly used stains and withstands high solvent concentrations in rapid destaining), immunoblotting, protein sequencing and nitrosylation studies

Application Note

A Practical Approach to Cell Signaling Pathway Analysis

Cellular kinase signal transduction pathways are involved in the regulation of many important cellular processes suchas cell survival, differentiation and apoptosis. Kinase signaling networks are typically characterized by multiple kinases arranged in cascades containing nodes with feedback loops, and crosstalk between pathways.



PolyScreen PVDF Transfer Membrane - Improved

The PerkinElmer Life Sciences, Inc. PolyScreen Transfer Membrane is a polyvinylidene fluoride (PVDF) microporous membrane for binding proteins that are transferred from a variety of gel matrices. This membrane is hydrophobic and offers a uniformly controlled porestructure with a high binding capacity for biomolecules. When compared to a nitrocellulose membrane, it has improved handling characteristics and staining capabilities, increased solvent resistance, and a higher signal-to-noise ratio for enhanced sensitivities.
