A DNA sequencer the size of a cell phone could change where, and how, gene research occurs. The DNA sequencer built by Oxford Nanopore draws power from a computers USB port. One day in 1989, biophysicist David Deamer pulled his car off Californias Interstate 5 to hurriedly scribble down an idea. In a mental flash, he had pictured a strand of DNA threading its way through a microscopic pore. Grabbing a pen and a yellow pad, he sketched out a radical new way to study the molecule of life. Twenty-five years later, the idea is now being commercialized as a gene sequencing machine thats no larger than a smartphone, and whose effects might eventually be similarly transformative. Early versions of the instrument, called the MinION, have been reaching scientific labs over the past few months after long delays (see 10 Breakthrough Technologies 2012: Nanopore Sequencing). Its built by a U.K. company, Oxford Nanopore, that has raised $292 million and spent 10 years developing Deamers idea into a DNA sequencer unlike any other now available. It is four inches long and gets its power from a USB port on a computer. Unlike other commercial sequencing machines, which can be the size … Continue reading →

Researchers at Johns Hopkins have identified a highly sensitive means of analyzing very tiny amounts of DNA. The discovery, they say, could increase the ability of forensic scientists to match genetic material in some criminal investigations. It could also prevent the need for a painful, invasive test given to transplant patients at risk of rejecting their donor organs and replace it with a blood test that reveals traces of donor DNA. In a report in the September issue of The Journal of Molecular Diagnostics, the research team says laboratory tests already show that the new analytical method compares favorably with a widely used DNA comparison technique. The researchers have applied for a patent. The current method for comparing DNA to determine paternity and advance criminal investigations counts the number of repeats in certain highly repetitive blocks of DNA that are not part of genes. But, says James Eshleman, M.D., Ph.D., a professor of pathology at the Johns Hopkins University School of Medicine, "Repeat testing will only detect DNA that makes up at least 1 percent of a DNA sample, so it's not great for situations in which results depend on small amounts of material within a larger sample." Making comparisons … Continue reading →
