Ion chromatography (IC) allows the determination of trace ions using low capacity high efficiency columns possessing fixed ion exchange sites. Combined with suppressed conductivity detection, IC yields parts-per-billion detection of the seven common inorganic anions (F-, Cl-, NO2-, Br-, NO3-, HPO42- and SO42-) and to a lesser extent carboxylic acids,…

Drug development has become more complex and significantly more expensive. There has been an estimated 55% increase in the critical path development costs since the year 20001. More than 50% of these costs are incurred in later phase development (Phase IIb and III studies).

To verify that cleanroom and clean zones are adequately installed and functioning they are usually validated during three occupancy states. First, when the installation is complete with all services connected and functioning, as-built; secondly during at-rest conditions when equipment is installed and running in a manner agreed upon by customer…

Although synthetic siRNA libraries are becoming more available, most high throughput siRNA library-based screening was carried out with siRNA libraries encoded by different vectors. In this article, siRNA library construction methods and HTS applications are summarised.

HCS has been implemented as a key technology to address complex biology associated with CNS drug targets. This review will describe a new generation of HCS assays including multiplexed HCS assays with biochemical markers, novel techniques for studying receptor internalisation and the application of HCS to neural network cultures that…

In spite of an increased understanding of brain mechanisms in recent years, there has been a lack of major new drugs being registered for psychiatric and neurological conditions1,2. To prioritise drug discovery resources and provide early proof-of-concept studies for novel compounds and mechanisms, the pharmaceutical industry is increasingly focusing on…

The proteome analysis started by the Human Proteome Organization (HUPO)1 is the second big international consortium project after the sequencing of the human genome by the Human Genome Project (HUGO)2. The aim of the HUPO Brain Proteome Project (BPP)3 is to derive in depth knowledge of the brain from analysing…

There can be no doubt that the FDA’s initiative on Process Analytical Technologies (PAT) has had an enormous impact on the pharmaceutical industries. However, the emergence of ’born again‘ PAT devotees in pharma companies has caused mild amusement in other industries where on-line analysis has been an integral part of…

Ultra high-throughput screening (UHTS) offers the possibility to discover novel pharmacophores. To benefit from UHTS special demands concerning assay quality and data analysis have to be met.

One major cause of the late failure of drugs in development (i.e. attrition) is the lack of clinical safety of the compounds (accounting for approximately 30% of failures together with toxicology)1. One of the key elements is the off-target effects of the compounds, causing adverse drug reaction (ADRs).

Since the 2000 publication of the PDA Technical Report Number 33 Testing Methods, rapid microbial methods (RMM) have not lived up to their promise for changing routine Quality Control microbiological testing in the pharmaceutical industry. With the next generation of rapid microbial methods emerging from the R&D laboratories of instrument…

Quantitative real-time PCR, the workhorse of any genomics lab, is a well established technique that has numerous uses due to its simplicity and flexibility. In this article we will review a brief history of real time PCR, discuss our strategy for optimising a lab running Quantitative-RT-PCR and describe how this…

Utilising man as a species for candidate drug selection is per se not a new concept, but the development of new technologies have made it possible to be realised in practice.

RNAi technology provides the ‘loss of function’ approach, which has been widely used in the last couple of years for analysis of gene function, and in drug discovery for identification and validation of potential drug target candidates. This technology is now widely applied for functional screens in order to identify…

The conclusion of the Genome Sequencing Project – far from providing the solution to the problem of human disease – has created further questions that had not previously been considered. Hence, the age of genomics has initiated the need to examine the body’s real biochemical actors: proteins, to learn about…
