Method to make paraffin-embedded breast and lymph tissue mimic fresh tissue in DNA analysis

Gene Expression Profiles from Formalin Fixed Paraffin Embedded Breast Cancer Tissue Are Largely Comparable to Fresh Frozen Matched Tissue

BACKGROUND AND METHODS Formalin Fixed Paraffin Embedded (FFPE) samples represent a valuable resource for cancer research. However, the discovery and development of new cancer biomarkers often requires fresh frozen (FF) samples. Recently, the Whole Genome (WG) DASL (cDNA-mediated Annealing, Selection, extension and Ligation) assay was specifically developed to profile FFPE tissue. However, a tho...

Method of Silver Impregnation for Nervous Tissue Embedded in Paraffin.

Tissue-preserving approach to extracting DNA from paraffin-embedded specimens using tissue microarray technology.

BACKGROUND DNA extracted from tumor cells or normal cells contained in formalin-fixed, paraffin-embedded tissues is widely used in many laboratories. The 2 most common procedures to isolate cells for DNA extraction from paraffin-embedded tissues are scalpel microdissection and laser capture microdissection. A new tissue- and time-conserving method for rapid DNA isolation from small cores taken ...

DNA 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...

Proteome 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 ...
