Quite often, leaking occurs during casting a gel for electrophoresis.  Even you have taken extraordinary care to make the glass plates and the spacers absolutely even, it sometimes still leaks.  It not only wastes your precious time, reagents and your sunny mood, but also leaves a nasty and toxic mess on bench for you to clean-up.   Such a painful game!

PrevoLeak prevents leaking completely and makes leaking a history in electrophoresis.  

PrevoLeak takes all the troubles off you, makes you easier than you think. Give it a try now.


  1. Very easy to use (see the instructions below), it takes no more than 10 seconds to apply PrevoLeak. No more any other steps are required.
  2. Leaves nothing behind on your gel, glass plates, PrevoLeak disappears naturally during running.
  3. No negative effect on running and your results.
  4. Non-toxic, wash your hands if you ever get any on.

  1. Squeeze PrevoLeak about 1mm high into the space along the bottom between the two glass plates, after assembling your gel cassette.
  2. Place the cassette on the gel stand as usual and do the rest.

PrevoLeak completely prevents leaking in either new or aged gel cassettes. To demonstrate the excellent stoppage, a strip of pH indicator was deliberately placed underneath a gel cassette. No leaking at all!



1. Each gel uses about 0.3g of PrevoLeak. A bottle of 60 grams can seal about 200 gels.

2. Store at room temperature.

3. PrevoLeak is clear.  The color shown here is for demonstration only.

Discard the liquid gently; remove the last drop of liquid on the tube opening by touching the tube opening on a paper tower. Add 200 ?l of Solution B, tap and keep the tube at room temperature for 1 minute to dissolve the pellet completely. The resulting DNA pellet can be visible or not depending on the copy number of a plasmid. You finish the whole process only in 1 tube for each sample and label your tubes once.


Plus2 SDS PAGE Kit

You are no longer to read your recipe, to make fresh ammonia persulphate, to hold your breath from stinky TEMED, to remember which ingredients added, to worry which ingredients missed or added less, and so on. Separating gels come with 4 concentrations of 8%, 10%, 12% and 15% or YOUR choice of concentrations in 7 ml tubes. With our kits, to make a gel, you simply pick up a base tube and add 2 solutions to the tube.



We suggest re-suspending a cell pellet from 1 ml of culture in 100?l of the PAGE running buffer and 100?l of 2x PAGE loading buffer. Cell lysates in SDS PAGE loading buffer are often sticky because of insoluble large molecules. After heating samples, shake well PAGE StreakFree and immediately add it to the sample at 10%. StreakFree solves these two problems and produces excellent protein profiles.
