The economical Navigator™ excels at all your blotting needs; Southerns, Northerns, Westerns, Chemiluminescent or Sequencing blots.
Three features set it apart: as a roller bottle-type blotter, it saves up to 90% on precious reagents compared to trays, but the Navigator goes one step further. Its patented tilting feature lets you concentrate the reagents over the blot, no matter how wide they are. Tilt back a few degrees from horizontal, put your blot to the bottom of the bottle and the small pool of reagent will stay over the blot rather than wandering on and off during rotation.
The second feature is intuitive and obvious but available nowhere else: "Make the bottle fit the blot." Most commercial blot developers offer one or two bottle diameters because if the bottles were any wider, the rotating rotisserie could not hold them. As a result, the filters must be rolled up with a nylon mesh to permit the exchange of reagent. The mesh increases buffer consumption and slows reagent exchange so starvation leaves shadows in Western and Chemiluminescent blots. Clearly, then, the best bottle for all types of blotting is one having a inner surface area that matches the size of the membrane so that every revolution bathes the entire surface of the blot in reagent.
But how to achieve such freedom? The answer is our patented MagnaBase™ bottle system. A strong magnetic disc on the bottom of our bottles holds them firmly to the rotating steel plate on the Navigator. As a result of this simple invention, one can...
• Change bottle sizes without changing clips.
• Use the entire surface of the plate and attain high holding capacity.
• Run several different sizes of bottles at the same time.
• See through our clear plastic lid to observe blot development progressing. |
