The OGC Array team has more than 10 years of experience in Genotyping, Gene expression and Methylation array technologies. We offer a flexible high quality service with fast turn-around time and the expertise to handle large-scale projects. Based on Illumina’s BeadArray iScan system and Affymetrix* GeneTitan microarray platform, we propose a range of applications to support small-scale and high-throughput studies. For project validation and targeted analysis we also offer a Fluidigm Biomark HD combined with an IFC controller HX as a walk-up platform.
We average 95 projects per year, ranging from a few hundred samples to projects of over 15,000 samples. Our total capacity is 100K-150K samples per year across the Affymetrix* and Illumina platforms, with sufficient staff flexibility to meet challenging deadlines.
The iScan system supports Illumina’s broad portfolio of genome-scale assays for genotyping, CNV analysis and methylation profiling.
We process Illumina array projects using automated workflows on the Tecan LIHA robot. BeadArray chips are scanned on two iScan dedicated scanning systems linked by an Illumina Autoloader 2.x to provide high sensitivity and throughput flexibility with 24-hour, walk-away data acquisition. Our experienced team can handle 1152 Illumina samples each week.

The high-density BeadArray and Infinium technology enables expanded genomic coverage for microarray techniques such as whole-genome genotyping (up to 5 million SNPs) and detection of large structural DNA changes. BeadChip arrays also support high sample throughput in targeted genotyping and DNA methylation analysis.
Infinium Genotyping Arrays
Illumina genotyping arrays allow for powerful genome-wide association studies, and can accurately detect point mutations, copy number variants, and chromosome aberrations. These microarrays enable a broad range of techniques, including human genotyping, custom genotyping, plant and animal genotyping, and cytogenomics.
Targeted arrays allow to genotype specific sets of targeted single nucleotide polymorphisms (SNPs), and focus research efforts on biologically meaningful variants. Microarrays with targeted content also enable greater throughput for screening large sample collections. Illumina offers a variety of disease-specific and population-specific array solutions for targeted genotyping.

Infinium Methylation Arrays
Genome-wide methylation profiling can help researchers to understand the functional mechanisms at work in complex disease cases. Illumina offers powerful solutions for studying heritable changes outside of the DNA sequence.
Illumina methylation arrays, covering the majority of RefSeq genes and CpG islands, allow researchers to quickly and accurately analyse and quantify methylation across the genome. The multi-sample array format, automation compatibility and low per-sample price make larger projects amenable to analysis.
As part of the workflow, we perform the conversion of methylated cytosine (5-mC) using the Cambridge Bioscience EZ DNA Methylation kit or hydroxymethyl cytosine (5-hmC) using the TrueMethyl CEGX kit (see Epigenetic analysis on Illumina EPIC arrays in Knowledge section). The assay then measures the proportions of cytosine and uracil at target sites for methylation.

Microarray Data Analysis
Illumina microarray software offerings include tools to facilitate experimental design, sample tracking and microarray data analysis, improving the speed and robustness of each study.
Illumina Genome Studio Infinium® Genotyping and Methylation
The Illumina GenomeStudio Genotyping and Methylation Modules allow analysis of data collected from Infinium® Genotyping and Methylation assays. The latest version of the Illumina GenomeStudio Software 2.0.2 is now used to perform genotype calling while Illumina GenomeStudio Software 2011.1 is still utilised for methylation profiling. (Genome Studio software). In each version, we undertake data QC but you can check your data directly with an easy-to-use Control Dashboard.
By default, at the end of your project you will be provided with a Genotyping or Methylation final report (.txt), a DNA report, samples table including call rate, image data (.idat) and a project summary Report with QC assessment. These cover all aspects of the experiment and highlight any poor samples or assays.

Researchers planning to screen dozens to hundreds of samples for dozens – or more – loci in custom panels should consider using the Fluidigm Biomark HD platform. By miniaturising and parallelising assays using a proprietary microfluidics device with nanolitre reaction volumes, it is possible to attain very high throughput and low cost per datatapoint with optimal sample use, or to reduce cost per sample while running only a few samples at a time.
Combined with the IFC controller HX, the assay options include the FLEXsix and 96.96 IFCs (information below from Fluidigm website).

The FLEXsix™ IFC
The FLEXsix IFC has six 12-assay-by-12-sample partitions that can each be run separately or together.
The 96.96 IFCs
These IFCs allow you to radically reduce hands-on time and total time to results while increasing the data accuracy of your gene expression or SNP genotyping studies. You get great data reliability and the microfluidic architecture does the heavy lifting, combining samples and assays into 9,216 parallel, 6.7nl PCR reactions. That’s up to 24 times what you get with a 384-well plate, and it only takes 15 minutes of hands-on time.
