EasyBeacons™ - new Probes Ideal for Realtime PCR Detection of Methylation Status of Single CpG Duplets and SNPs
K. Skadhauge, C. Nielsen & U.B. Christensen

The EasyBeacons™ presented here are based on the novel technology Intercalating Nucleic Acid, INA®, linked to a fluorophore and a quencher. INA® is composed of normal DNA nucleotides and Intercalating Pseudo Nucleotides (IPNs). The fact that the EasyBeacons™ are mostly composed of normal DNA nucleotides means that in many respects EasyBeacons™ behave like DNA based probes, allowing use of standard buffers, primers and enzymes and hence reduces the optimisation efforts.

Real-time PCR in Diagnostics of Plant Viruses
Mehle N., Boben J. and Ravnikar M.

Sensitive and specific method real-time PCR was developed for diagnostics of certain plant viruses. Real-time PCR can be used for determination of different viruses as well as for differentiation between related strains of viruses. The method can also be used for detection of low concentrations of plant viruses in various samples such as environmental waters, growth substrates and seeds.

Real-Time Multiplex Rt-PCR on Circulating Tumor Cells
Anieta M. Sieuwerts, Stefan Sleijfer, Jaco Kraan, Joan Bolt-de Vries, Jan-Willem Gratama, John WM Martens and John A. Foekens

Using the CTC kit (CellSearch™), cells that attached to anti-EpCAM Moab were immunomagnetically separated and used for analysis of a selected pilot set of 32 genes by real time RT-PCR. This study shows the feasibility of multiple gene expression analysis on RNA isolated from only one tumor cell. Most importantly, expression analysis of several tumor-specific genes in blood samples containing only 2 tumor cells is already possible.

Novel Fluidics Microbead Trap/Flow Cell Enhances Speed/Sensitivity of Bead-Based Bioassays Up to 5-Fold
RM Ozanich, CJ Bruckner-Lea, JW Grate, MG Warner, BP Dockendorff, KC Antolick, HC Edberg, LH Johnson, AN Easterday

Pacific Northwest National Laboratory (PNNL) has developed a micro/nano particle trap that allows surface-functionalized magnetic or non-magnetic particles to be trapped with subsequent perfusion of sample, reagents and wash solutions, yielding significant (up to 5-fold) improvements in assay speed and sensitivity, while significantly reducing sample matrix effects.

Utilizing High Speed Photography to Optimize Low Volume Dispensing Conditions
Mary Cornett, Mitch Gordon and Anca Rothe

In this study we use high-speed photography as a feedback mechanism for adjusting the Nanodrop instrument dispense settings to improve the positional dispense accuracy of low volume (nanoliter) drops. These same parameters can be investigated, with various fluid classes, to reduce deleterious effects on dispensing performance such as deflected streams, satellite formation, secondary pulses and drop deformation.
