whatman PVDF膜

Whatman Westran™ PVDF (Polyvinylidine Fluoride) membranes are available in two formats: the Westran S used for protein sequencing and the Westran Clear Signal used for Western blotting

Westran S
Westran S PVDF is a 0.2 µm pore size hydrophobic membrane designed specifically for protein sequencing applications. The small pore size of this membrane eliminates ‘blow-through’ and increases protein binding over a wide range of molecular weights.

Features and benefits
  • Protein binding capacity (over 200 µg/cm2) for easy signal detection
  • Chemical resistance needed for N-terminal sequencing
  • High protein retention even after harsh wash steps
  • Maximum capture of proteins during transfers minimizing sample loss
  • 0.2 µm pore size for higher surface area, resulting in better binding of low molecular weight proteins
  • Compatible for use with Western blotting applications
  • Available in popular precut sizes for your application

Westran clear signal
Westran Clear Signal (CS) PVDF is a 0.45 µm membrane specifically designed for Western blotting and protein dot-blotting applications.

Features and benefits
  • Protein binding capacity over 125 µg/cm2
  • Extremely low backgrounds with chemiluminescent and colorimetric applications providing you with clear signals and sharp bands
  • Excellent results with general protein stains such as Coomassie® Brilliant Blue, Amido Black, and Ponceau S Red
  • Increased strength allows for multiple stripping and reprobing, which results in savings

Westran blotting sandwiches
A precut PVDF membrane and 2 sheets of 3MM Chr blotting paper are prepackaged into a sandwich to help save time. Sandwiches are available with either Westran S or CS.
