After addition to an FFPE sample, the solution remains on the sample while proteinase K digestion is carried out. An optimized xylene-free protein extraction method adapted to formalin-fixed paraffin embedded tissue sections for western blot analysis. Product Details. Water-based deparaffinization is a green alternative. Comprised of pretreated tubes and a rack system to reduce pipetting steps, the system eliminates the need for hazardous chemicals and minimizes loss of tissue sample.
