protein arrays

The Cambridge, Mass.-based firm will use its microarray technology to screen proteins for drug leads.

Protagen will focus on developing serum-based molecular diagnostic tests for early detection of multiple sclerosis and for differential diagnosis of prostate cancer.

The company will use the investments to develop its protein array for multiple sclerosis and prostate cancer.

The "carbon-on-metal" technology would address limitations to gold as a material for protein array development, making such arrays less susceptible to non-specific binding, less prone to denaturing proteins, and more reusable.

The Madison, Wis.-based company’s imaging systems analyze protein arrays made on gold biochips, which enables label-free analysis that may “accurately reflect how proteins function in real life,” the company said.

CEO Stefan Muellner told BioArray News last week that Protagen has shifted its business strategy from developing tests on its UniArray protein chip platform to discovering panels of biomarkers that can later be brought to market by bigger firms.
