Tissue microarrays (TMAs) are widely used to analyze gene expression in multiple pathological samples on a single slide. Currently, most TMA slides are made by coring paraffin-embedded tissues and arraying them into a paraffin block, from which TMA sections are cut. However paraffin-based TMA technology may not be compatible with frozen clinical tissue samples, which have a higher quality of RN...

  Background and Objectives:  The molecular genetic of the human herpes virus 8 (HHV8) has now been characterized the pathogenesis of kaposi sarcoma (KS). This study attempted to determine the rate of HHU-8 infection in KS in an Iraniann cross sectional study. Method & material: In this cross-sectional study, we used paraffin-embedded specimens of 54 clinically well-characterized kaposi sarcom...

As part of an investigation aimed at illuminating the possibilities and limits of the HOPE-fixation and paraffin-embedding technique we here describe a novel procedure which was developed in order to combine the benefits of the HOPE-technique with the capabilities of laser microdissection. The presented procedure avoids the need for amplification of template-RNA thus facilitating reliable and r...

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...

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...
