DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

New biosensor offers fast detection of H5N1 in farm air

As highly pathogenic H5N1 avian influenza continues to spread in the U.S., posing serious threats to dairy and poultry farms, both farmers and public health experts need better ways to monitor for infections, in real time, to mitigate and respond to outbreaks.

Biodesix partner, Friends of Cancer Research, publishes data in Clinical Cancer Research, demonstrating strong association between ctDNA changes and treatment outcomes for patients with solid tumor types

Biodesix, Inc, a leading diagnostics solutions company, and Bio-Rad Laboratories, a global leader in life science research and diagnostics products, contributed to new research findings from Friends of Cancer Research's (Friends') ctMoniTR Project, recently published in Clinical Cancer Research (CCR). The findings demonstrate a strong association between changes in levels of circulating tumor DNA (ctDNA) and treatment outcomes, offering the potential for integration of ctDNA analysis in therapeutic development programs, and clinical cancer care.
