Chromatin is a nucleoprotein complex, found in eukaryotic organisms, consisting of approximately 50% DNA and 50% histone proteins. The histones undergo a number of reversible covalent chemical modifications (for example, acetylation, methylation, phosphorylation), especially in the N-terminal regions. These chemical changes prepare chromatin for a range of essential cellular processes…

Differential scanning calorimetry (DSC) is a widely used technique within the pharmaceutical industry because the range of phase transitions it can measure usually allows near complete physical characterisation of a new active principal early during preformulation. In addition, because DSC measures a property change that is ubiquitous† (heat) there are…

Advanced Aseptic Processing (AAP) is a term referenced in the recently published ISPE RABS definition1 to cover the spectrum of Restricted Access Barrier Systems (RABS) and isolator systems. In general, AAP techniques are physical barrier methods of product protection and containment that are used during manufacturing operations to separate (primarily)…

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…

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…

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…

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…

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…

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…

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…
