DNA can signal the presence of or predisposition to a slew of diseases, including cancer. The ability to flag down these clues, known as biomarkers, allows medical professionals to make critical early ...

Article reviewed by Govind Kaigala, PhD at the University of British Columbia. Stay up to date on the latest science with Brush Up Summaries. In situ hybridization (ISH) is a molecular technique that ...

Tau protein is a collection of closely related polypeptides that associate with microtubules in vivo and stimulate their assembly in vitro. Using an affinity-purified antiserum against bovine brain ...

Part of the device is coated with single strands of DNA. When these "probes" encounter DNA biomarkers that have a corresponding, or complementary, genetic sequence, the two strands bind, sending a ...

Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to ...

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...

Next-generation sequencing (NGS) has made analyzing DNA faster and cheaper, with effects felt in the lab, clinic, and beyond. A set of newly-launched technologies are offering a twist on the chemistry ...

In health care, paper-based diagnostics have revolutionized point-of-care approaches by providing disposable, low-cost tools that can be used remotely. Developed by the World Health Organization (WHO) ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...
