To construct a tissue microarray, small core biopsies are taken from viable, morphologically representative areas of paraffin-embedded tumor tissues and assembled on a recipient paraffin block.

Formalin-fixed, paraffin-embedded tissue blocks from 45 consecutive cases from 1990 to 1994 of high-grade serous carcinoma of the ovary were selected.

Paraffin microtomy is performed on routine as well as tissue microarray blocks. The thickness of sections ranges from 3-4 um for both H&E staining and immunohistochemistry. We also perform high ...

March 15, 2006 (Vol. 26, No. 6) Emphasis on Potential Clinical Applications and Enhancing RNA Sample Quality Researchers are beginning to look at tissue microarrays (TMA) from different ...

The histotech uses the microtome to cut thin sections of the paraffin block containing the biopsy specimen. ... The quality of the tissue sections is not as good as those of the permanent section.

For this, the tissue sample is preserved and subsequently dehydrated and embedded in paraffin blocks. Further on, thin tissue sections of the samples are produced and applied to glass slides.

This is routinely achieved by placing the paraffin blocks on ice, cooling both the tissue and the wax to a similar consistency and swelling the tissue to make it easier to section. As the block ...

Each tissue microarray is constructed from paraffin-embedded (FFPE) tissue blocks from a specific number of donor cases. Additionally, the microarrays come in various configurations, with a range of ...

Precision for Medicine offers an extensive inventory of pathologist-reviewed FFPE tissue blocks, slides, curls, cores, and tissue microarrays from both normal and diseased subjects, all collected ...

This is routinely achieved by placing the paraffin blocks on ice, cooling both the tissue and the wax to a similar consistency and swelling the tissue to make it easier to section. As the block heats ...

Recent improvements in technology have provided the opportunity to use formalin-fixed paraffin-embedded tissue (FFPET) biopsies for reliable GEP. 17 We recently reported the feasibility of applying a ...
