Protein separations – key platforms

	Bioprocessing – columns Our bioprocess systems (instruments, media and software) are used by leading pharmaceutical and biotech companies for the industrial manufacture of over 90 per cent of the biopharmaceuticals on the market or in development. The wide range of chromatography columns includes Chromaflow™ and Streamline™ brands.		Bioprocessing – separations media Consumables used in bioprocessing. Leading brands include Sepharose™, MabSelect™, and Source™.
	Bioprocessing – membrane separation Hollow fibre filtration membranes used in bioprocessing – an essential step for removing impurities in biologically-based drugs.		Laboratory separations ÄKTA™ platform – the gold standard in chromatography systems for laboratory purification of proteins before scale-up to manufacturing.
Discovery systems– key platforms
	Genomics DNA sequencing: MegaBACE™ DNA sequencer for decoding the genetic structure of human, animal and plant species. TempliPhi™ template preparation kit for producing DNA samples. Gene expression: CodeLink™ pre-arrayed slides and Lucidea™ custom slides platform, on which thousands of DNA samples are scanned to identify differences in the way genes are expressed.		Bioassays Instruments include LEADseeker™, which has the ability to screen up to 1,000,000 new drug compounds a day, and IN Cell Analyzer, which enables scientists to study the effects of a potential new drug on living cells in real time. Products also include a range of custom-labelled reagents for toxicology testing.
	Proteomics Ettan™ high throughput protein analysis platform utilising systems such as mass spectrometry and electrophoresis to identify and characterise proteins, and to compare protein expression in diseased and normal tissues, enabling drugs to be targeted to diseases. Products also include the CyDye™ range of fluorescent dyes.		Informatics Scierra™ platform of software solutions for managing and organising the vast amounts of data being generated in life sciences research.
