Southern and Western Blotting Membranes
Protran membranes are ideal as Southern and Western Blotting Membranes.
Whatman Nytran Nylon Membranes come in two formats, Nytran N and Nytran
SuPerCharge (SPC). Nytran N is
- Ideal for applications that require a lower charge
- Designed for Southern blotting and Northern blotting
- Also can be used for colony lifts and plaque lifts.
Nytran SPC nylon membranes have a very high positive charge, but are manufactured with a process that allows a combination of high positive charge with low background. Whether using radioactive or non-radioactive detection techniques, Nytran SPC consistently gives high signal with extremely low background.
Whatman Optitran Nitrocellulose Membranes consist of 100% pure nitrocellulose cast onto both sides of an inert polyester support material. These membranes offer:
- Excellent signal-to-noise ratios
These characteristics make Optitran ideal for Western blotting or other applications that involve repeated antibody stripping and reprobing.
Whatman Westran PVDF Membranes are available in two formats, Westran S used for protein sequencing and the Western Clear Signal used for Western blotting. Westran S PVDF is a 0.2um pore size hydrophobic membrane designed specifically for protein sequencing applications. The small pore size of this membrane eliminates
- Increases protein retention over a wide range of molecular weights
Western Clear Signal PVDF is a 0.45 µm membrane specifically designed for Western blotting and protein dot-blot applications
