Purdue proves concept of using nano-materials for drug discovery

... smaller molecules to pass. "This allows us to do separation right in the reactor, which means we can do reactions that could not be done before in such a small device. We can study membrane proteins in a fundamentally new way, which is very important because many future drugs to treat diseases will likely wor...

Integration of Agilent's MS technology, Proteome Systems' software to help scientists in proteomics research

...sts and more laboratories. Using Agilent's protein separation and LC/MS products and Proteome Systems' GlycomIQ software, life scientists will be better able to produce, analyze and integrate complex data on the forefront of proteomics research." ...

Breakthrough isolating embryo-quality stem cells from blood

...minute. This is not yet fast enough for industrial separation of millions of high grade stem cells, but it promises a realistic alternative to embryo use if it can be scaled up. Meanwhile, it is already being used to isolate low-grade stem cells which can develop into skin. In collaboration with medical profess...

Retrovirus struck ancestors of chimpanzees and gorillas millions of years ago, but did not affect ancestral humans

...n three and four million years ago, well after the separation of humans from apes. That split is estimated to have occurred five to seven million years ago. During that period, ancestral humans were likely to be living in the same area of Africa as great apes. African apes may have been susceptibile to the viru...

'Punctuated' evolution in the human genome

...romere, which plays a critical role in chromosomal separation during cell division. Pericentromeric regions contain an abundance of segmental duplications, which are large DNA sequences that exhibit strong similarity to the euchromatic ancestral loci from which they were copied. According to Eichler, the limite...

Picky female frogs drive evolution of new species in less than 8,000 years

...ntly had diverged enough during their million-year separation that offspring of southern females and northern males failed to develop beyond the tadpole stage. Though crosses involving northern females and southern males successfully produced frogs, the offspring developed more slowly than the offspring of pair...

'Perception' gene tracked humanity's evolution, scientists say

...f genes known to have tracked or guided humanity's separation from the other apes is a short one. Genes controlling the development of the brain almost always turn out to be identical or nearly so in chimpanzees and human beings. And as it turns out, the protein prodynorphin is identical in humans and chimps. ...

Twin molecular scissors link creation of microRNAs with gene-silencing

...ever," Shiekhattar says. "All of the activity ?the separation of the strands, the multiple cutting steps, everything ?is being done in the absence of any energy use." Instead, he says, the different molecules involved have stronger and weaker affinities for each other that govern their stepwise associations an...

Multi-million pound UK Biobank underway

...cially designed automated systems for blood sample separation and for storage, retrieval and tracking of around 10 million biological samples, which must be kept at between -80?C and -200?C for several decades. When UK Biobank is running nationwide, this robotic system will need to handle samples taken from aro...

Enzyme crystal structure reveals 'unexpected' genome repair functions

...re were no specific models for how XPB acts in DNA separation either to initiate transcription or to begin NER. There were also no models for the role that XPB, which is an essential subunit of Transcription Factor IIH (TFIIH) functional assembly complex, might play in changing conformations for TFIIH's alterna...

ANU scientists crack DNA replication mystery

So Lin and his research team started looking for technologies that would create an easier, more efficient and more economical process. They were also ...

Slow-frozen people? Latest research supports possibility of cyropreservation

...lular ice formation which leads to dehydration and separation into the ice and concentrated unfrozen solution. If we could, by slow cooling/warming, supercool and then warm the cells without the crystallization of water then the cells would be undamaged." ...

Molecular DNA switch found to be the same for all life

...rcase" of the DNA to deform as a first step in the separation and unwinding of its two gene-carrying strands. "It is likely that the AAA+ rings of the replication initiators are open to allow others proteins to dock onto the initiator complex," said Berger. "These other proteins can help add layers of comp...

A protein complex that untangles DNA

...in, makes the chromosomes more compact, making the separation easier", says Camilla Sjögren. The research group has studied the third, less well understood, protein complex, known as the Smc5/6 complex. This protein complex was found to bind to locations on the DNA strand that the researchers had artificiall...
