KALAMAZOO, Michigan — Armune BioScience, which is developing protein-based diagnostic tests for certain cancers, added $400,000 through debt and other securities, according to a filing with the Securities and Exchange Commission.
The funding follows a $1.1 million angel round the 1-year-old startup closed in August 2008. Soon after that round the company opened a research lab at the Medical Research Institute in Ann Arbor.
Armune is developing a test to detect cancer by finding evidence of the immune response to cancer. Its first product tests for prostate cancer, but it is also developing lung and breast-cancer tests.
