Is Immobilon-FL better than Nitrocellulose membrane for Fluorescence detection?
Yes. Background fluorescence of Immobilon-FL is typically 2-5X lower than that of nitrocellulose, thus improving signal-to-noise ratio (sensitivity). Nitrocellulose membranes have other disadvantages. If allowed to dry out, they become brittle, tend to fracture and are difficult to handle. They are not recommended for stripping and re-probing. Nitrocellulose blots need to be scanned as soon as possible after detection, as diffusion of signal on a wet membrane may also occur.
