BOULDER, CO — InDevR, a Boulder-based life science company, has

received a new NIH SBIR grant to develop an innovative optical system that will automate

interpretation of hemagglutination assays. The 2-year Phase 1 grant (R43AI106054) is sponsored by

the National Institute of Allergy and Infectious Diseases.

Hemagglutination and hemagglutination inhibition assays are widely used to characterize viruses and

related antibodies. For example, the hemagglutination inhibition assay is the gold standard for

determining antibody levels produced in response to an influenza vaccine. Both assays rely on

manual interpretation of red-blood cell aggregation in the presence of virus, which can lead to error in the measurement. The product in development at InDevR is designed to automate results

interpretation and provide a more accurate and precise measurement.

“We are delighted to receive support from NIAID to develop an automated hemagglutination

analyzer. This new product is part of our dedicated effort to advance vaccine development and

manufacturing through cutting-edge analytical tools that provide improved results at reduced

cost,” said Dr. Kathy Rowlen, InDevR’s CEO.

According to Rowlen, there is a robust National initiative to improve influenza vaccine

manufacturing. The hemagglutination inhibition assay has been identified as a problematic step in

influenza vaccine characterization. Currently hemagglutination plates are read “by eye”, with a user

carefully inspecting each well in a 96-well plate and manually recording the results. While many of

the assay preparation steps can be automated, plate reading is exclusively manual and represents a

bottleneck in the process. The automated hemagglutination analyzer under development at InDevR

is based on a proprietary optical design (patent pending) with custom software that will enable rapid assessment of each well in a hemagglutination plate and output of a digital record. Automation of plate reading will eliminate the current bottleneck and streamline analysis.
