Laboratory Technologist [Ref 26758] – Waltham, MA

Exosome Diagnostics is a privately held company focused on developing and commercializing revolutionary biofluid-based diagnostics to deliver personalized precision healthcare that improves lives. Exosomes are messengers released by all living cells into biofluids, such as plasma/serum, urine, cerebrospinal fluid and saliva, forming a highly enriched source of RNA, DNA and proteins from their cell of origin. Our proprietary exosome-based technology platform can yield comprehensive and dynamic molecular insights about cells in the body without direct access to the actual cells. Through this novel technology, we are focused on transforming how cancer and other serious diseases are detected, diagnosed, treated and monitored. In 2016, we will launch multiple diagnostics, including liquid biopsy tests for lung, prostate and other solid tumor cancers.
