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 کاملFlow Cytometric DNA Analysis and Histopathologic Re-Evaluation of Paraffin Embedded Samples from Hydatidiform Moles and Hydropic Abortions
Background Distinction of hydatidiform moles (HMs) from non-molar abortions and sub-classification of HMs are important for clinical practice; yet, diagnosis based solely on morphology is affected by interobserver variability. The objective of this study was to determine the role of DNA flow cytometry in distinguishing molar from non-molar pregnancies. MaterialsAndMethods This retrospective stu...
متن کاملLaser scanning cytometry can complement the flow cytometric DNA analysis in paraffin-embedded cancer samples: a paradigmatic case.
Archival studies on paraffin-embedded tumor samples are often complicated by difficulty obtaining a reliable diploid DNA standard. Nontumor cells, e.g., inflammatory and stromal cells, most often found interspersed among tumor cells, would represent a solution to this problem. Unfortunately, there is an inherent difficulty to positively identifying tumor cells in paraffin-embedded specimens. Us...
متن کاملTissue-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 ...
متن کاملEnhanced fungal DNA-extraction from formalin-fixed, paraffin-embedded tissue specimens by application of thermal energy.
Determining the etiology of invasive fungal infections (IFI) is critical for patient management as fungi vary in their susceptibility to antifungals. However, the etiology remains obscure in many cases due to negative culture results. The identification of fungal DNA by PCR in pathology blocks and sequencing it is an alternative approach to determine the cause of IFI. Previous studies identifie...
