Deparaffinize and rehydrate by immersing the slides through the following solutions/ wells: Draw a circle on the slide around the tissue with a hydrophobic barrier pen. Do NOT use with the Visium assay for snap frozen and OCT embedded tissue. Bioz Stars score: 97/100, based on 1 PubMed citations. 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 . Afterwards, the slides were immersed in a bath of 100% alcohol twice for three minutes . See this image and copyright information in PMC. Summary of Findings: For mineral oil-deparaffinized specimens, decreasing the duration of proteinase K digestion from 72 h to 1 h had no effect on DNA yield, purity or mean DNA fragment size. Let tissues fix in 10% formalin at room temperature for 8 hours but not to exceed 24 hours. Speed up your next big discovery. 3 min. J Biomol Tech. After addition to an FFPE sample, the solution remains on the sample while proteinase K digestion is carried out. Rinse with running tap water for 30-45 minutes. Deparaffinization in EZ prep 75C 8 minutes. JoVE publishes peer-reviewed scientific video protocols to accelerate biological, medical, chemical and physical research. Find Breakthroughs Faster with the Freedom to Discover. Epub 2021 Jan 14. Before proceeding with the IHC staining protocol, the slides must bedeparaffinizedandrehydrated.
