MALDI FT-ICR MS platform for proteomics: Rationale for an offline approach and optimised implementation

19 July 2008 | By

MALDI FT-ICR MS platform for proteomics: Rationale for an offline approach and optimised implementation A number of sophisticated approaches have been developed to study the structure and function of genes, including the whole-scale sequencing of entire organisms[1], global transcriptional profiling[2], and forward genetic studies[3]. However, these techniques are ultimately limited…

High content imaging subpopulation analysis for phenotypic drug discovery

19 June 2008 | By

Phenotypic drug discovery (PDD) has come of age – again. Using a microscope to observe a cell, one of the oldest techniques available to a cellular biologist dates back to the 17th century studies of Antony van Leeuwenhoek and his characterisation of ‘animalcules’. These early analyses, which simply described the…

In vitro toxicity screening as pre-selection tool

19 June 2008 | By

Drug discovery relies on massive screening of compound libraries with in vitro cell-based target assays. These pharmacological screens have been well accepted. For in vitro toxicological screening, this privilege has only been obtained for the Ames, chromosomal aberration and eye irritation tests. At the moment, a number of cellular assays…

Platform technology for routine three dimensional cell culture

19 June 2008 | By Dr Stefan Przyborski, Chief Scientific Officer, ReInnervate Ltd, School of Biological and Biomedical Science, Durham University

Cell culture assays play an important role during the first stages of pharmaceutical development. The design of such in vitro models is significant and data resulting from such tests directly influences the progression of compound development. Therefore it is becoming progressively more important to design cell culture assays that are…

Peracetic acid in the study of rhIL-11 methionine oxidation

19 June 2008 | By

Recombinant human interleukin-eleven (rhIL-11) is a pleiotropic cytokine which stimulates stem cell proliferation and affects multiple cell types1. The protein has been demonstrated to provide clinical benefit in platelet restoration2 and Crohn’s disease3. rhIL-11 is a highly basic protein that is rich in arginine, leucine and proline residues, lacks disulfide…

Lyophilization: cycle robustness and process tolerances, transfer and scale up

19 June 2008 | By Serguei Tchessalov and Nicholas Warne, Wyeth BioPharma, Andover

During the past 10-15 years, close attention has been paid to the development of optimal lyophilization cycles for different types of pharmaceuticals1-4. Recent advances in process control, such as the Smart Freeze-DryerTM technology or similar approaches, [5-7] make cycle development a routine procedure. The attention of many researchers has shifted…

Wyeth’s PAT variations submitted through the EMEA Worksharing Procedure

19 June 2008 | By Graham Cook PhD, Senior Director, Process Knowledge/Quality by Design, Wyeth Pharmaceuticals

In June 2006, the EMEA called for nominations from companies to participate in the pilot phase of a worksharing exercise for Quality variations1. Worksharing is a key element in the revisions to the variations proposed by the European Commission, which are intended to streamline the process for making changes to…

MicroRNAs for high-throughput functional analysis

19 June 2008 | By

MicroRNAs (miRNAs) are a class of small non-coding RNA molecules, which are potent post-transcriptional gene expression regulators. They have been shown to participate in the regulation of numerous cellular processes, the list of which is still growing. miRNAs affect numerous targets that can be determined by direct experiments or predicted…

PAT – reducing the cost of quality in consumer products manufacturing

19 June 2008 | By

The ease in making process analytical measurements (typically spectroscopic) in manufacturing has provided a unique opportunity to obtain up-to-date information for making timely process correction decisions. At-line methods provide near-time information without the need for elaborate process control interfacing upfront. This approach works well for batch processing applications or unit…

Implementation, validation and registration of rapid microbiological methods

19 June 2008 | By

Over the last decade, interest in rapid microbiological methods (RMMs) in the pharmaceutical sector has grown considerably. Technologies such as ATP bioluminescence, solid phase laser cytometry and genetic-based identification systems are being vigorously investigated. Validation and regulatory requirements for such new technologies are beginning to emerge. However, there is a…
