Array och analysfaciliteten är ett samarbete mellan Uppsala universitet och Akademiska laboratoriet.


The Affymetrix technology

GeneChip probe arrays are manufactured using technology that combines photolithography and combinatorial chemistry.

Expression analysis

- Whole-Transcript Gene Expression & Alternative Splicing

Affymetrix whole-transcript gene expression and alternative splicing solutions allow you to measure gene expression at the transcript and exon level.

- 3' Gene Expression

The GeneChip® Human Genome U133 Plus 2.0 Array offers comprehensive analysis of genome-wide expression on a single array. Eleven pairs of oligonucleotide probes are used to measure the level of transcription of each sequence represented on the array.

 - miRNA

 - Formalin fixed paraffin embedded samples

This method provides the latest and most robust RNA amplification and labeling solution for whole-genome expression profiling from FFPE samples.

Expression assays can be run on cartridge arrays or on our new system:

GeneTitan® Multi-Channel (MC) Instrument

The GeneTitan Instrument automates array processing from target hybridization to data generation by combining a hybridization oven, fluidics processing, and state-of-the art imaging device into a single bench-top instrument.


- Axiom Genotyping

Axiom Genotyping Solution includes pre-designed and customized array plates with validated genomic content from the Axiom Genomic Database as well as complete reagent kits, data analysis tools, and a fully automated workflow utilizing GeneTitan® Multi-Channel (MC) Instrument.

Copy number analysis

- Fresh or fresh frozen samples

The GeneChip SNP arrays are dual-purpose arrays, simultaneously providing both copy number predictions and genotypes for loss of heterozygosity (LOH) determination.

The high density of markers on these arrays enables identification of gains and losses with increased confidence because of the many data points predicting even the small copy number aberrations. The availability of genotyping data makes the detection of LOH possible.

 - Formalin fixed paraffin embedded samples

A new exciting possibility is to study allele-specific genomic copy numbers using Formalin Fixed Paraffin Embedded (FFPE) samples. Until recently fresh or fresh frozen samples have been required for genomic copy number analysis using SNP arrays. With the introduction of OncoScan™ technology based on molecular inversion probes also the many FFPE tumor samples stored in biobanks can now be analyzed.

In a pilot study we have been able to obtain allele-specific copy number information from 37 out of 52 ovarian cancer samples. These samples have been difficult to analyze with conventional methods (CN info from 10 out of 52 samples). Thus, we think that this technology will be important to obtain results from large cohorts also of relatively rare tumors. So if you are interested in studying the genomes of tumors in FFPE samples, get in touch with us and we will be able to tell you more.

 - CytoScan HD Cytogenetics Solution

The CytoScan HD Solution provides the broadest coverage, highest performance, and most "genotype–able" single nucleotide polymorphisms (SNPs) for detecting human chromosomal aberrations associated with genes related to constitutional and cancer cytogenetics, OMIM, and RefSeq. This single array includes more than 2.6 million copy number markers of which 750,000 are "genotype–able" SNPs and 1.9 million are non–polymorphic probes.


We offer all types of services from the initial consultation, performing the complete array experiments to analyzing the results.

Since we are focusing on using the commercially available Affymetrix technology we provide all types of analysis for the applications available. We have many years’ experience  of expression analysis, copy number analysis of tumor samples and methylation data analysis so we can offer service and support on all steps of the analysis procedure here including experimental design, quality control, normalization, visualization, various statistics and evaluation of the results and integrating different data types.

Forskning och utveckling

Our aim is to develop and apply bioinformatic tools to describe and understand biological processes involved in human disease so that improved treatments can be developed. We focus on how to use large-scale molecular data including microarray data to obtain these goals. In practice it means that we are involved in two types of research acivities.

1) Bioinformatic tools

We develop improved bioinformatic tools that can provide better answers to relevant research questions.

Our efforts to develop new bioinformatic tools have been focused on three major areas over the last few years: genomic aberrations in tumor cells, non-coding RNAs from RNAseq data and improved performance estimation.

Identification of genomic aberrations in tumor cells

The goal is to identify copy number aberrations in tumor cells in clinical tumor samples. However there are a number of issues that makes this task difficult. Often large proportions of non-tumor cells are present in the sample. Tumor cells are often aneuploid complicating normalization. Different tumor cells may also have different aberrations.

Whole genome sequencing data

We have developed a bioinformatic tool called Patchwork that uses whole-genome sequencing data from cancer samples to obtain segments with allele-specific copy numbers.

Mayrhofer M, DiLorenzo S, Isaksson A. 2013. Patchwork: allele-specific copy number analysis of whole genome sequenced tumor tissue. Genome Biol. Mar 25;14(3):R24

SNP array data

We have also developed one bioinformatic tool called Tumor Aberration Prediction Suite (TAPS) identifies allele-specific copy numbers and loss-of heteozygosity from SNP array data, even in the presence of large proportions of non-tumor cells and aneuploidy.

2) Data analysis

We apply publically available tools or those we have developed ourselves to perform data analysis for particular biomedical applications.

Our efforts to analyze data in biomedical applications fall into two broad categories: Analysis of genomic DNA, mRNA expression and/or methylation in tumor samples and Identification of mRNA biomarkers in various types of samples

Analysis of genomic DNA, mRNA expression and/or methylation in tumor samples
