Quantifying protein-protein binding
30 November, 2012 by Daniel Some, Principal Scientist, Wyatt Technology CorporationComposition-gradient static light scattering can be used to determine the binding affinity and stoichiometry of reversible protein complexes, without tagging, immobilisation or other modifications. The method can distinguish and quantify multiple simultaneous stoichiometries.

Agrisera Protein Extraction Buffer with Precellys homogeniser for plant and algal protein isolation
27 July, 2012Protein Extraction Buffer (PEB) from Agrisera is designed for the solubilisation of total protein from plant tissue and algal cells. The use of the anionic detergent LDS increases the quantity of solubilised and non-degraded proteins.
Chemists develop more efficient protein labelling
09 February, 2012North Carolina State University researchers have created specially engineered mammalian cells to provide a new ‘chemical handle’ which will enable researchers to label proteins of interest more efficiently, without disrupting the normal function of the proteins themselves or the cells in which they are found.
Proteomics and the formation of long-term memories
07 February, 2012Memories are maintained by synapses, the connections between neurons, but how do these synapses stay strong and keep memories alive for decades? Neuroscientists at the Stowers Institute for Medical Research have discovered a major clue from a study in fruit flies: hardy, self-copying clusters or oligomers of a synapse protein are an essential ingredient for the formation of long-term memory.
Shimadzu PPSQ series protein sequencer
25 November, 2011Shimadzu’s PPSQ series achieves greater simplicity and reliability in the automatic determination of amino acid sequences by employing HPLC analysis coupled with high sensitivity detection and powerful acquisition/analysis software.

World’s largest artificial protein synthesised
16 November, 2011Ten days of continuous processing by 400 of Vanderbilt’s supercomputer processors were needed to ascertain the most stable configuration of the largest human-built protein. The designed protein, containing 242 amino acids, has been synthesised and inserted into E. coli.
Oxford Expression Technologies superSf9 cells
17 October, 2011 byThe superSf9 cells from Oxford Expression Technologies offer improved recombinant protein yield using the baculovirus protein expression system. The superSf9 cells are transgenic insect Sf9 cells that have been engineered to stably express an additional protein. The presence of this protein leads to prolonged longevity after infection with baculovirus and up to a 15-fold increase in recombinant protein production in baculovirus infected superSf9 cells compared with standard Sf9 cells.
