Novel role of protein in dementia

Scientists have identified a novel protein which, when over-expressed, leads to a dramatic increase in the generation of Aβ.



Breakdown of the KRas protein

KRas is one of the usual suspects in cancer. It is a protein that is mutated in 30% of human tumours and has been implicated in the regulation of many cell signalling pathways.



Key protein in cellular respiration discovered

Researchers have discovered a new function for a protein in the mitochondrion that plays a key part in cell respiration.



Protein may aid cancer spread

A protein called Muc4 may be the essential ingredient that allows breast cancer to spread to other organs and resist therapeutic treatment.



Protein signalling pathway protects for life

A protein signalling pathway recently discovered to guide the formation of the skeleton in the foetus also keeps bones strong through adult life.



New protein discovery

Scientists have now managed to identify a protein that opens new possibilities of understanding both APS-1 and other autoimmune disorders.



Protein inhibits Ebola

Scientists have identified a protein, ISG15, that inhibits the Ebola virus from budding, the process by which viruses escape from cells and spread to infect neighbouring cells.



Parkinson's protein

Scientists studying rats displaying a form of Parkinson's disease discovered that a protein in brain cells can be toxic if it lacks a phosphate.



Structure of protein collagen

The structure and behaviour of one of the most common proteins in our bodies has been resolved at a level of detail never before seen.



Finding the key to protein folding

One of the enduring mysteries about proteins is how they manage to fold into the novel 3D shapes that give them their functional qualities. Two new pieces of research are shedding light on this fundamental biochemical process.



New ion trap mass spectrometer boosts protein characterisation

Anew ion trap liquid chromatograph and mass spectrometer (LC/MS) that allows scientists to study proteins in a manner that was previously achievable only on a million-dollar floor-standing instrument that requires a dedicated operator.



Parallel protein purification workstation is a world first

The ability of Australian scientists to study the molecular structure and function of proteins has taken a leap forward with the announcement that the world's largest parallel protein purification workstation is to be housed at Monash University in Victoria.



Modular system for high-throughput protein purification

After completion of the human genome project, proteomics research has increasingly attracted the attention of the scientific community. However, progress in this field has been restrained by the difficulties encountered in isolating and purifying proteins from complex samples.



Custom Yeast two-hybrid screens for protein interactions

The yeast two-hybrid system has become an increasingly important tool to identify and map novel protein-protein interactions.



Collagenous protein: an important nutrient for joint and bone health

Against several opinions that gelatine has no nutritional value, it is known today and proved by several scientific and clinical studies that collagenous protein is an important nutrient especially for the health of bones and joints. Annelore Schott reports.



Affinity chromatography is vital to protein research and development

Because they are derived from living organisms, biological products present a potential source of pathogens. By John M. Curling.



Sample purification kits for mRNA and protein

Now available from Bio-Nobile Oy is a range of kits for the purification of nucleic acids and proteins, based on BN's magnetic particle separation technology.



Anti-tumour protein research success

Lately, success stories have originated from anti-tumour protein research and human embryonic stem cells research.



Imaging crystalline protein grains in 3D using X-ray diffraction

Preparing protein crystals has always been difficult because their growth mechanisms are not well understood. A better insight into these mechanisms is now possible, using a new imaging method based on coherent x-ray diffraction.



low protein cell culture media

The use of serum-free media has been well established in tissue culture. It is commonly used to culture many cell lines, including primary cells, cancerous cells, and various transfected cells.
