Argon to Improve Bioanalyte Stability in Fixed Tissue Specimens

Abstract: The degradation of archival surgical and biospecimen limits the utility of many biomarkers that may have prognostic or predictive significance in guiding a patient’s therapy. Previous methods at preventing the degradation of RNA and proteins in formalin fixed, paraffin embedded (FFPE) tissue blocks & slides have no protective benefit. Researchers...

Novel Fixative for Improved Biomolecule Quality from Paraffin-Embedded Tissue

Abstract: Tissues samples collected during medical procedures, such as biopsies, are used to diagnose a wide variety of diseases. Before diagnosis, patient samples are typically processed by fixation and paraffin embedding. This fixation/embedding process is used to preserve tissue morphology and histology for subsequent evaluation. Unfortunately, most...

Ratio Based Biomarkers for the Prediction of Cancer Survival

Abstract: The AKT pathway plays a key role in the regulation of cellular survival, apoptosis, and protein translation and has been shown to have prognostic significance in a number of cancers. Recently, the inventors have identified several functions of the AKT pathway in certain cancers, such as extrahepatic cholangiocarcinoma (EHCC). The NCI seeks...

Module to Freeze and Store Frozen Tissue

Abstract: Tissue obtained for both clinical and research purposes is routinely frozen, commonly in Optimal Cutting Temperature (OCT), an embedding media, for eventual downstream analysis, commonly including sectioning on a cryostat. Though OCT is the standard compound used for freezing, there is no standard freezing protocol. Thus, current methods of...

A Specialized Tissue Collection Device for the Preservation and Transportation of Needle Biopsies

Abstract: The ability to hold and transport tissue, especially needle biopsies in a pre-defined and controlled environment is critical for the preservation of biopsy samples in downstream analytic applications. Currently, tissue specimens are placed in open containers with variable, poorly controlled solutions applied to them, often in less than sterile...
