Dealing with the Deluge

Flow cytometry is a technique for cell characterisation that is popularly used in basic and translational research for understanding, for example, how mutated stem cells may confer therapy resistance to a tumour (1). Alternatively, cell characterisation can be used to measure cell receptors during activation or as a response to immunosuppressive drugs. A flow cytometer consists of a narrow, hydrodynamically-focused stream of cells that pass and are interrogated by a light source. The cellsí physical characteristics of size and granularity, as well as any fluorescent labels attached in or on the cells, scatter the beam of light. Fluorescent labels attached will then be excited, enabling the appropriate emission characteristics to be measured in relative terms of fluorescent intensity.

Flow cytometer manufacturers have responded to the needs of modern researchers by developing faster systems that can measure more variables over shorter time periods for applications such as detecting tumour cells in peripheral blood and examining different aspects of stem cell differentiation. However, the ability of the software that flow cytometers rely on to analyse and visualise the rapidly rising tide of data now being generated has lagged way behind these improvements in instrument technology. This article examines some of the approaches that enlightened software manufacturers are now taking to speed up and simplify data analysis and support the revolution in flow cytometry research.

York Health Economics Consortium offers an updated training event

Health economics evidence is a key element in much health services research and particularly in health technology assessments, including submissions for NICE single technology appraisals. Identifying economic evidence to inform submissions involves searches in a range of databases and uses a variety of strategies.

Challenges of Analytical Method Transfer in the Pharmaceutical Industry

RSSL

The development and validation of suitable analytical methods is a critical part of the overall drug-development life-cycle. For the majority of products, particularly those that are clinically successful, the transfer of the analytical method between laboratories will be required. This process is designed to verify that a given laboratory is capable of performing a test method for its intended purpose. This can be performed either internally (at the same company), or, with the on-going increasing trend in outsourcing, to an external Contract Research or Development organisation (CRO or CDO).
