SUPPLEMENTARY INFORMATION: Technology description follows.
    Title of Invention: Improved Fixative for Paraffin-Embedded Tissue 
Samples.

Description of Technology

    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 fixative agents damage or destroy nucleic acids 
(RNA and DNA) and proteins, thereby potentially impairing diagnostic 
assessment of tissue.
    Researchers in the National Cancer Institute's Laboratory of 
Pathology have developed an improved tissue fixative solution that is 
formaldehyde-free. This fixative, BE70, significantly improves DNA, 
RNA, and protein biomolecule integrity in histological samples compared 
to traditional fixatives. Additionally, BE70 is compatible with current 
protocols and does not alter tissue processing. In vitro an in vivo 
data are available and the fixative has been tested on paraffin-
embedded samples.

Potential Commercial Applications

     Improves integrity of fixed tissue samples.
     Improves RNA/DNA quality in fixed tissue samples.
     Non-cross linking, improves protein quality.

Value Proposition

     There is substantial interest in new fixatives to replace 
neutral buffered formalin (a carcinogen) as primary fixative agent for 
surgical pathology.
     BE70 overcomes several limitations of other fixatives, 
including cost and disposal issues.
     Could be formulated as a concentrate, and marketed as an 
additive (to be added during dilution of ethanol).

Development Stage

    In vivo data: YES.
