Proteomic Sample Preparation from Formalin Fixed and Paraffin Embedded Tissue
Preserved clinical material is a unique source for proteomic investigation of human disorders. Here we describe an optimized protocol allowing large scale quantitative analysis of formalin fixed and paraffin embedded (FFPE) tissue. The procedure comprises four distinct steps. The first one is the preparation of sections from the FFPE material and microdissection of cells of interest. In the sec...
متن کاملProteome Analysis of Formalin - Fixed and Paraffin - Embedded Tissue
Title of dissertation: PROTEOME ANALYSIS OF FORMALIN-FIXED AND PARAFFINEMBEDDED TISSUE Tong Guo, Doctor of Philosophy, 2008 Dissertation directed by: Professor Cheng S. Lee Department of Chemistry and Biochemistry Because of the long history of the use of formalin as the standard fixative for tissue processing in histopathology, these archival formalin-fixed and paraffinembedded (FFPE) tissues ...
متن کاملWhole-Genome Gene Expression Profiling of Formalin-Fixed, Paraffin-Embedded Tissue Samples
BACKGROUND We have developed a gene expression assay (Whole-Genome DASL), capable of generating whole-genome gene expression profiles from degraded samples such as formalin-fixed, paraffin-embedded (FFPE) specimens. METHODOLOGY/PRINCIPAL FINDINGS We demonstrated a similar level of sensitivity in gene detection between matched fresh-frozen (FF) and FFPE samples, with the number and overlap of ...
متن کاملUnravelling the proteome of formalin-fixed paraffin-embedded tissue.
Biofluid detectable biomarkers that originate at the site of diseased tissues would be advantageous, in that, they may provide mechanistic information concerning the manifestation and progression of the disease. Unfortunately, tissue biopsies are precious samples that can generally be acquired in small amounts due to the invasive nature of the sample collection. One of the foundations of pathol...
متن کاملDNA extraction from formalin-fixed, paraffin-embedded tissue.
Several DNA extraction methods have been used for formalin-fixed, paraffin-embedded tissues, with variable results being reported regarding the suitability of DNA obtained from such sources to serve as template in polymerase chain reaction (PCR)-based genetic analyses. We present a method routinely used for archival material in our laboratory that reliably yields DNA of sufficient quality for P...
