The initial step, common to all FFPE sample preparation protocols, is deparaffinization, and the protocol used in most laboratories is essentially the reversal of the paraffinization procedure, comprising many steps that cannot be readily automated and are time-consuming: e.g., sequential washing steps with xylene and decreasing concentrations . 0 endstream endobj startxref 0 %%EOF 113 0 obj <>stream Rinse slides in PBS 3X, 5 minutes each time. please visit our Contact Us page.
