RNA: Converting imaging-based cell biology to high-throughput biology

19 February 2014 | By Juha K. Rantala, Department of Biomedical Engineering and Knight Cancer Institute, Oregon Health and Science University

The last 10 years in biomedical research marks the period of deepening our understanding of the human genome. In the context of cancer research, The Cancer Genome Atlas (TCGA) and related international genomics efforts have now revealed the full complexity of genomic aberrations in human cancers that are postulated to…

Improving the quantitation of live antigens used to produce rabbit generated serotype specific antiserum

21 February 2013 | By Michael J. Miller, President, Microbiology Consultants, LLC, Silvia Fragoeiro, Ananthi Ramachandran and Paul van Empel MSD Animal Health

This is the first paper in our continuing series on Rapid Microbiological Methods (RMM) that will appear in European Pharmaceutical Review during 2013. Flow cytometry represents one of a variety of viability-based RMM technologies that are currently available to the pharmaceutical industry. In flow cytometry, individual particles are counted as…

Figure 5: VHP can stratify CVD status. The profile computationally combines EPC and MP measures. In the upper panel, the vertical axis represents a measure of a subpopulation of endothelial microparticles and the horizontal axis a measure of EPCs

At the crossroads: The next decade

26 April 2012 | By J. Paul Robinson, Purdue University Cytometry Laboratories & Weldon School of Biomedical Engineering, Purdue University; Bernd Bodenmiller, Group leader, Institute of Molecular Life Sciences, University of Zurich; Valery Patsekin and Bartek Rajwa, Purdue University Cytometry Laboratories, Purdue University; and V. J. Davisson, Medicinal Chemistry & Molecular Pharmacology, Purdue University

Flow cytometry is the technology that has the most impact on single-cell analysis. Over the past 40 years, it has arguably been the single most important research technique in the fields of basic and applied immunology. Flow cytometry excels in quantitative evaluation of receptor expression, separation of functionally defined cell…

Implementation of flow cytometric biomarker assays in clinical development

20 June 2011 | By Dianna Y. Wu & Russell Weiner, Clinical Biomarkers and Diagnostics, Merck & Co

Biomarker research has become one of the integral aspects in drug discovery and development. It is broadly utilised to confirm drug mechanism of action (MOA), explore PK/PD correlation, support dose selection and predict response to treatment. Therefore, biomarker data provide valuable information to guide clinical decisions, support drug filings with…

Figure 1 A: Control B: Docetaxel treated Induction of apoptosis with Docetaxel compared to untreated. The lower right quadrant represents cells in early apoptosis and cells in the upper right quadrant are cells in late apoptosis due to PI entering the cells through leaky membranes. C: Control D: Docetaxel treated Cell cycle of control cells and Docetaxel treated cells. The first peak shows cells in G0/G1 and the second peak is cells in G2/M. The breast cancer cell line, MDA MB231, was treated with 10nM docetaxel or DMSO control for 72 hours. Cells were harvested, the nuclei isolated and stained with PI. Samples were run on the LSR II flow cytometer and analyed in FCS Express software. Docetaxel arrests the cells in G2/M

Application of flow cytometry in drug discovery

16 December 2010 | By Dana Buckman, Senior Scientist, Biomarkers – Translational Research, Pfizer

Flow cytometry can be used to advance our understanding of diseases in multiple ways. Drug effects and dosages can be ascertained in vitro, along with patient selection based on mutations and antigen profiles. Within the Diagnostic Biomarkers group of Translational Research at Pfizer, we are utilising flow cytometry in conjunction…
