Protein precipitation is an important step prior to many experiments in the biology, biochemistry and cell biology laboratories. This step is also required for concentration of proteins if total protein concentration is below detection limits. It is also required when buffer exchange is necessary and for partial purification of proteins. To be useful, the procedure must be reproducible, permit high protein recovery, be simple to perform and cost effective. ITSIBIO has developed a product that is the most reliable, reproducible, easy-to use and cost effective in the market.

The easy-to-use Protein Precipitation Kit (ToPREP) is specifically formulated for precipitation of proteins from solution with higher than 90% recovery. It contains the ProPreCip protein precipitation booster, optimized reagents, and standard operating procedure. This allows research scientists to easily, conveniently, and reproducibly precipitate total proteins or perform buffer exchange. The precipitated protein is suitable for 1D-PAGE, 2D-PAGE, 2D-DIGE, and western analysis.
