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.

Detection of Genetically Modified Organisms Using DNA Microarrays
Jaroslava Ovesna, Katerina Demnerova and Lucie Vistejnova

With the increasing production of genetically modified organis ms (GMOs ), the quick detection syst em is required. Microarrays offer a suitable and time saving method. Our aim is to develop DNA microarrays for detection of GMOs.

Gene Expression in Cold-stressed Barley as Detected by Microarray Analysis
J. Ovesná, B. Svejkovská, L. Kuèera, M. Malý, M. Herbstová and L. Cattivelli

Goal of this work is to find genes in spring and winter barleys that are influenced by cold stress and to analyze their expression profiles during stress. A few of experiments reported influence of temperature on the leaves and crown nodes, that is why we focus our study also on crown nodes by microarray technology.

A Novel Array- Based Assay for the Detection of Ig G-Mediated Food Intolerance
Andrew Macdonald, Michael J. Walker, Michael S. Walker and Julie G. Reeve

We have developed a microarray based immunoassay to permit both greater food panel diversity and higher throughput testing. The Genarrayt™ 200+ Foods IgG test comprises of glass slides onto which 16 microarrays of over 200 different foods have been printed. Each microarray includes standards for quantitation and positive and negative controls for quality control. Food IgGs are detected by a novel fluorescent dye labelled anti-human IgG conjugate and results are measured using a laser scanner.

Usage of Low-Density Oligonucleotide Microarrays for Prognosis Prediction of Colorectal Cancer Patients
Slabý O., Garajová I., Svoboda M., Fabian P., Svoboda M., Šmerdová T. and Vyzula R.

This study aimed to find individual up/down-regulated genes associated with progression and metastatic potential of colorectal cancers using low-density oligonucleotide microarrays spotted with genes known to be involved in process of metastasis development. We suppose that focusing on a particular biological pathway may be more useful than genome-wide screening for our purposes.

Diagnosis of Aortic Aneurysm from Gene Expression Profiling of Peripheral Blood
Catalin Barbacioru,Yulei Wang, Dov Shiffman, Olga Iakoubova, Sriram Balasubramanian, Julie Blake, John Elefteriades and Raymond Samaha

We report in this study that gene expression profiles of peripheral blood cells may allow early detection and diagnosis of aortic aneurysm. Gene expression profiles of peripheral blood samples collected from 58 individuals diagnosed with thoracic aortic aneurysm (cases) and 36 normal individuals (controls) were analyzed using the Applied Biosystems Expression Array Systems and Human Genome Survey Microarrays.

Microarray Analysis Using Competitive Hybridization
J. Bishop, C. Wilson, A. M. Chagovetz and S. Blair

In this work we explore the effects of wild-type and single nucleotide polymorphism (SNP) target specie concentrations, temperature, and the time of hybridization on sensing specificity in two component systems. A finite element method is used to simulate the diffusion of DNA through a microfluidic chamber to the sensing surface of bound oligonucleotide probes where hybridization of DNA is modeled using the corresponding chemical reaction equation assuming low grafting density.

T7 Amplification for Generating Single Stranded Target for Hybridization to Allele-Specific DNA Microarrays
Jesper Petersen, Lena Poulsen, Henrik Birgens and Martin Dufva

Amplified RNA (aRNA) synthesized by T7 linear amplification is frequently used for gene expression analysis on microarrays. Single stranded DNA (ssDNA) is however mostly used as target in microarray based genotyping assays, although there are several advantages with aRNA. Here, we compared the performance of aRNA and ssDNA as targets in a genotyping assay, comprising a DNA microarray of allele specific oligo probes specific for thalassemic mutations.

Quality Monitoring on Human 14K Oligo Chips at the University of Calgary
Xiuling Wang, Stephen M. Robbins and Mayi Arcellana-Panlilio,

The production of microarrays needs to be carefully monitored and quality control tests done to track systematic effects and performance variations over time to maximize the possibility of getting high quality data.
