Influence of decalcification on immunohistochemical staining of formalin-fixed paraffin-embedded tissue.

An enhanced antigen-retrieval protocol for immunohistochemical staining of formalin-fixed, paraffin-embedded tissues.

Formalin is the most commonly used fixative for light microscopy because of its preservation of -morphological details. A major adverse effect of formalin fixation is formation of cross-linkages between epitopes (amino acid residues) and unrelated proteins by formaldehyde groups. The great majority of monoclonal and polyclonal antibodies used for immunohistochemical (IHC) staining of formalin-f...

Influence of clearing agent on immunohistochemical staining of paraffin-embedded tissue.

Unravelling 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...

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 ...

Antibody validation and scoring guidelines for ABCG2 immunohistochemical staining in formalin-fixed paraffin-embedded colon cancer tissue

Overexpression of the ATP-dependent drug efflux pump ABCG2 is a major molecular mechanism of multidrug resistance in cancer and might be a predictive biomarker for drug response. Contradictory results have been reported for immunohistochemical studies of ABCG2 protein expression in colorectal cancer (CRC), probably because of the use of different antibodies and scoring approaches. In this study...
