Hot Start Amplification using OligoBeads via Gradual Release of Bound Primers
Dr. Nam Ngo, Dr. Laurent Jacquinod

OligoBeads provide a mean to store normalized primers used in performing enzymatic reactions including PCR. Primer bound beads eliminate the potential for pipeting errors and reduce contamination thus yielding lower repeat rates and less reagent wastage. The primers bound to the OligoBeads can be stored over a period of a few months without degradation in a nuclease free environment.

Target length effect on sensitivity and specificity of oligonucleotide microarrays: Advantages of a modified PCR based labelling method over the dendrimer technology.
Abdullah Gibriel1*, Walter Kolch2 and Andrew Pitt1,3

Several methods have been developed for target labelling to enable DNA microarray quantification without taking careful consideration for target length effect. This report highlights the importance of choosing the optimum target length that would ensure specificity without compromising sensitivity of the assay. It also shows the advantages of using the modified PCR method over other methods in generating labelled amplicons of the desired lengths to maximize hybridization efficiency.

On chip micro-extraction and real-time PCR with integrated SPAD optical fluorescence detection for nucleic acid analysis
Cristina Potrich, Elisa Morganti, Nicola Massari, Lucio Pancher, C. Kostoulas, Laura Pasquardini, Cristian Collini, Andrea Adami, Lorenzo Lunelli, F. Kalatzis, David Stoppa, Cecilia Pederzolli, Leandro Lorenzelli

A PDMS lab-on-a-chip for one step DNA isolation and real time-polymerase chain reaction (RT-PCR) has been designed, fabricated, and characterized for point-of-care clinical diagnostics. In addition, a module for on-chip optical detection based on SPAD - Single-Photon Avalanche Diode - detector has also been developed and used to monitor the presence of specific DNA polymorphisms possibly related to genetic diseases.

Chemical Variant of 7-deaza-dGTP for Improved CG-rich PCR Amplification
E. H. Ashrafi, S. Shore, T. Le, V. Timoshchuk, N. Paul, R. Hogrefe, G. Zon, I. Koukhareva, A. Lebedev

PCR amplification of nucleic acids is a fundamental technique used in many molecular biology laboratories. Despite its wide use, certain GC-rich regions of DNA, such as mycobacterial disease targets, still remain a challenge for amplification. Sequences high in GC content are associated with the formation of secondary structure, which prevents adequate strand separation and DNA polymerase amplification. As a consequence, mispriming is prominent, complicating specific product formation.
