NEC plans DNA analyzer for nearly-instant results

(Phys.org)—NEC is working on a DNA analyzer that is the size of a suitcase, portable enough to be taken to crime scenes. The NEC analyzer integrates all steps required in DNA analysis. By 2014, NEC intends ...

New method for sequencing genome in a single cell

(Phys.org)—The traditional genome sequencing process requires thousands of cells (or more) to provide sufficient DNA, and this means that variations that are only present in a small number of cells―such as early cancer ...

Researchers give mutants another chance

Researchers at Fox Chase Cancer Center have demonstrated that it might be possible to treat genetic diseases, including some forms of cancer, by "rescuing" the misshapen, useless proteins produced by some mutant genes.

Researchers develop new sensor for methylated DNA

Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation—the addition of a methyl group of molecules to a DNA strand—is ...

Monitoring Cancer Cell Changes With Quantum Dots

One of the earliest events that changes a normal cell into a malignant one is known as deoxyribonucleic acid (DNA) hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes. A team of investigators ...
