miniDAWN TREOS II SEC-MALS Detector for Essential Protein and Polymer Characterization

Wyatt Technology, the world leader in instrumentation for absolute macromolecular and nanoparticle characterization, announces the launch of its next generation multi-angle light scattering (MALS) detector for SEC/GPC, the miniDAWN® TREOS® II. The TREOS II is the only SEC-MALS detector for size exclusion or gel permeation chromatography that offers full field serviceability, extended ease-of-use, and a built-in upgrade path from HPLC to UHPLC technology.

New imaging technology catches DNA naturally fluorescing

Many of the secrets of cancer and other diseases lie in the cell's nucleus. But getting way down to that level -- to see and investigate the important genetic material housed there -- requires creative thinking and extremely powerful imaging techniques.

Elucidating IDP behaviour on crowded membranes

IDPs are proteins that contain stretches of amino-acid sequence that are flexible and do not comprise stable structure in isolation. This is in contrast with a more traditional view of proteins as largely occupying a stable native structure that correlates with functions such as enzyme activity or binding.

Neutrons key to discovering new HIV drugs? An interview with Dr Matthew Blakeley

Neutron crystallography allows us to determine the three-dimensional structures of biological macromolecules, such as proteins, by means of the diffraction of neutrons from the regularly spaced atoms of a crystal.

Researchers reveal DNA unwrapping can happen asymmetrically to expose specific genes

The protein complex that holds strands of DNA in compact spools partially disassembles itself to help genes reveal themselves to specialized proteins and enzymes for activation, according to Rice University researchers and their colleagues.

Chloride switch controls critical step in basement membrane formation

Chloride plays a key role in the formation of the basement membrane, a suprastructure on the outside of cells that undergirds and guides the function of most of the tissues of the body.

Unlocking the dark proteome: an interview with Dr Kriwacki

The term dark proteome refers to proteins whose structural features and thus functions are not well understood. Many proteins within the dark proteome do not fold into stable three-dimensional structures. These proteins are called intrinsically disordered proteins (IDPs) and feature highly flexible, disordered confirmations.

Scientists develop new strategy to combat wide range of viruses

Scientists and health officials are marshalling forces to fight Zika, the latest in a string of recent outbreaks. Many of these efforts target that virus specifically, but some researchers are looking for a broader approach. Now one team reports in ACS' journal Macromolecules a new strategy to fight a wide range of viruses that appears to be safe in vivo and could evade a virus's ability to develop resistance.
