    FAQ

    QuestionAnswer
    How many times can I strip and reprobe Immobilon-P?While 2-3 times is probably the limit, it is difficult to give an absolute number in regards to stripping and reprobing. This is because there are many factors to consider when it comes to protein binding to PVDF and primary antibody affinity to these proteins. Different proteins will have varying degrees of affinity to PVDF. This is based on factors discussed in our Protein Blotting Handbook (see TP001; Protein Binding section). One round of stripping may remove one protein and leave another intact. The same could occur when using different primary antibodies. Different antibodies will have varying affinities to different proteins. If carrying out several rounds of stripping and reprobing, one strategy might be to detect the least abundant proteins earlier leaving the higher abundant proteins later for detection.
    What is the difference between Immobilon–FL and Immobilon-P?Both membranes are made from PVDF. The difference in background fluorescence is due to proprietary modifications in the membrane manufacturing process.
    How does the protein binding capacity and protein retention of Immobilon-FL compare to Immobilon-P?Immobilon-FL’s protein binding capacity and protein retention are comparable to Immobilon-P.
    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.
    What fluorescence-based detection methods can be used with Immobilon-FL?Immobilon-FL can be used in Western blotting applications using either fluorescent dye-conjugated antibodies or chemi-fluorescence substrates. Western blots can be imaged in the visible or IR range. Single color detection or multiplexing for co-localization studies can be performed efficiently on Immobilon-FL Fluorescent proteins, e.g. green fluorescent protein, (GFP) or proteins tagged with GFP, blotted onto the membrane can be readily detected as well.
    What is the level of detection sensitivity when using Immobilon-FL?Immobilon-FL exhibits the lowest background fluorescence of any blotting membrane thus improving the signal-to-noise ratio (sensitivity) of any fluorescent dye. The fluorescence signal is dependent on the fluorescent dye used, thus the ultimate sensitivity of detection is determined by the dye itself. With Immobilon-FL the sensitivity is not limited by the membrane, e.g., detection of proteins in the low picogram level has been observed with QDot® Nanocrystals fluorescent-tagged antibodies on Immobilon-FL.
    What fluorescent dyes are recommended to use with Immobilon-FL?Immobilon-FL membrane exhibits very low background fluorescence over a broad range of wavelengths and can be used with all visible and infrared fluorescent dyes. Generally, dyes with larger Stokes shift (greater separation between absorption and emission wavelengths) are preferred in western blotting applications using fluorescence-based detection. NOTE: To prevent photo-bleaching, protect the membrane from light during secondary antibody incubations and washes until the membrane is ready to be scanned.
    What are the recommendations for two-color western / multiplex detection?The two antibodies must be derived from different host species, so that they can be differentiated by secondary antibodies of different specificities. Before combining the two primary antibodies test their banding patterns on separate blots to know where to expect the bands. Use highly adsorbed cross-adsorbed secondary antibodies in two-color detection. Refer to the directions provided with the detection reagents for additional details.
    How long does the fluorescent signal stay on the developed blot?The fluorescent signal from fluorescence-tagged antibodies will remain stable on the membrane for several months, or longer, when stored protected from light. The membranes may be stored dry or in PBS at 4ºC. The fluorescent signal from chemi-fluorescent substrates does not remain for long so blots using these substrates need to be scanned immediately.
    Are there specific recommendations on using 'low fluorescent’ reagents (buffers, blocking agents, etc.) with Immobilon-FL?Immobilon-FL has been tested with the most commonly-used blocking reagents and buffers such as TBST, PBST, dry milk, BSA, casein and buffers recommended by the fluorescence scanner manufacturers, e.g., Licor Odyssey buffers. All were found to be compatible with fluorescent detection on Immobilon-FL. However, as in any western blotting experiment, optimization of blocking reagents and buffers may be required, depending on the nature of the antigen, antibodies and fluorescent dyes used. The use of freshly prepared buffers is always recommended.
