Tissue microarrays from HOPE-fixed specimens allow for enhanced high throughput molecular analyses in paraffin-embedded material.

ABSTRACT

In this study, we describe a technique that allows for the production and the use of tissue microarrays (TMA) from HOPE-fixed, paraffin-embedded specimens. The combination of these two technologies unites the advantages of the high throughput aspects in TMA, with good preservation of nucleic acids, proteins, and morphology of HOPE-fixed tissues, thus substantially widening the capabilities presently available for molecular studies in paraffin-embedded tissues.
