Biotage Initiator+ Alstra automated microwave peptide synthesiser
07 September, 2012Biotage has introduced an innovative synthesis platform for peptide researchers. The Biotage Initiator+ Alstra is a fully automated, single-channel, programmable microwave peptide synthesiser.
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.
GE Healthcare Amersham ECL GEL Box electrophoresis system
24 November, 2011The GE Healthcare Amersham ECL GEL Box buffer sparing electrophoresis system offers high resolution and sensitivity for optimal performance for protein detection.
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.
Oxford Expression Technologies pOET transfer plasmids
16 August, 2011 byOxford Expression Technologies has released four pOET transfer plasmids which encode for 6xHis-Tag fusion sequence and the pOET Sequencing Primers.
Lonza PAGEr Gold precast polyacrylamide gels
22 July, 2011 byPAGEr Gold Precast Gels are designed for optimal separation of a wide range of proteins. They contain a stacking gel and a resolving gel for separating denatured and native proteins.
Sage-N Research signs microbial identification agreement
06 June, 2011Sage-N Research has signed an exclusive agreement with the US Army Edgewood Chemical Biological Center (ECBC) to license technology for microbial identification.
Beckman Coulter protein characterisation application note
25 May, 2011The application note ‘Assay Of IgG Purity And Heterogeneity Using High-Resolution Sodium Dodecyl Sulfate Capillary Gel Electrophoresis’ highlights the development of both a new polymer formulation and standardised methodology to assess the purity and heterogeneity of IgG and its isoforms.
Odyssey Thera compounding profiling service
20 April, 2011 byUsing cutting-edge Protein-fragment Complementation Assay technology from Odyssey Thera, Lonza is able to offer profiling services that can shape and influence critical decisions about drug candidates.
Innova Biosciences imm-Link Immunogen Linking Kits
20 April, 2011Innova Biosciences imm-Link Immunogen Linking Kits simplify the conjugation of haptens to carrier proteins. Large immune responses are stimulated by BSA, ovalbumin and keyhole limpet hemocyanin (KLH) and are typically used as carrier proteins to generate antibodies against small antigens (eg, peptides or organic compounds - ie the ‘hapten’). To successfully stimulate the production of antibodies, the antigen needs to be covalently linked to a carrier protein.
