In a proof-of-concept study, scientists at Delft University of Technology in the Netherlands and the University of Illinois have successfully repurposed DNA nanopore sequencing technology to scan ...

While DNA sequencing is a useful tool for determining what's going on in a cell or a person's body, it only tells part of the story. Protein sequencing could soon give researchers a wider window into ...

A major step has been taken toward the sequencing of proteins, demonstrating the accurate identification of amino acids, by briefly pinning each in a narrow junction between a pair of flanking ...

While researchers have already succeeded in obtaining sequence information from single DNA strands, a further major challenge in bioanalytics is the direct determination of the amino acid sequence ...

Proteins are the workhorses of cells and provide vital insights to cell health and disease function. Immunoassays and mass spectrometry are well established methods for studying proteins and have led ...

Whether you’re interested in why a living system works as it does or the reasons it goes awry, proteins are a critical part of the molecular picture. The proteins circulating in a person’s plasma can ...

Amino acid sequencing has become a highly automated and efficient process. It plays an invaluable role in protein biochemistry, and is making an increasing contribution to modern molecular biology and ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...
