How to use Technologies offered

A search for a cancer, preclinical stage, synthetic opportunity would use the selection "Therapeutics, Diagnostics" in 'Sector', 'Cancerous, neoplasmatic' in 'Disease Category', 'Drugs, Small Molecule' in 'Technology' and 'Preclinical' in 'Development Stage'.

Selection of 'Enabling Technology, Platform Technology' in 'Sector' will identify all kinds of research technologies that can be used in more areas of life sciences than pharmaceuticals only.

Each technology profile gives the name of a company or academic institute as source of the offer, and a link allowing to contact the potential licensor. In most cases a profile includes a pdf covering the available non-confidential information as well as detailed contact data.

Registered users can create non-public notifications profiles which will inform them about new 'Technologies Offered' entries fitting their needs as specified. In addition these profiles allow them to filter the available information more comfortably.


High-Throughput Cell Based Assay for the Identification of Drugs Targeting the NF-kB Signaling Pathway

Organization name

National Jewish Health



Researchers at National Jewish Health have developed a microscopy-based visual assay to measure the antigen-receptor activation of an intermediate molecule located upstream of NF-kB

Potential Applications

Identification of compounds as potential agents against inflammatory diseases, immune diseases and cancer

Advantages of Invention

The assay targets Bcl10, a specific intermediate protein of the NF- kB pathway, and it is compatible with epifluorescence/confocal microscopy

State of Development

Using cell lines developed in-house, National Jewish Health scientists have demonstrated that T cell receptor activation of NF-kB involves the dynamic relocalization of the signaling intermediate Bcl10. This protein movement can be visualized by confocal or epifluore scence microscopy using a fluorescent marker (such as GFP) or antibodies.
