Global analyses platform - Illumina Deep Sequencing
Illumina Genetic Analysis Platform - Helmholtz Centre for Infection Research (HZI), Braunschweig, Germany
The HZI Illumina infrastructure is part of the Department of Genome Analysis of the HZI, one of the 16 large research organisations of Germany. The facility includes several robotic systems, large scale genome sequencing instruments (two Megabases, one HITACHI, four long range sequencers) including the most recent addition of an Illumina Genetic Analysis Platform. Highlights for digital gene expression tag profiling using Illumina analyser are:
No sequence knowledge required: Universal platform to study any transcript
Tuneable coverage: Almost unlimited dynamic range for rare transcript discovery
Sensitivity: Four million tags per sample yields an average of 12 counts for transcripts at one copy per cell
Orthogonal validation: Genome-wide data comparable to qPCR validation of microarrays.
The members of the infrastructure have more than a decade of experience in high-throughput genome sequence analysis. This involves large-scale DNA sequencing, bioinformatics and robotics including technology development. The department has been involved in a number of international and national genome projects.
As partner in TRANSVAC, HZI offers deep sequencing and comparative transcriptome analysis service based on the Illumina platform in the form of samples (RNA/DNA) analyses to be provided by external Users. The Users shall also be trained on site.
Training for two Users at a time
- theoretical and practical sample preparation (duration two days)
- demonstration of sequencing process
- theoretical and practical training of data processing (duration two days)
Modalities of access
Organisation short name: HZI
Unit of access: One sample (a sample of RNA, in a few cases DNA) to be analysed by Illumina Platform for sequencing and or transcriptome mapping on contract.

Input – sample requirements:
RNA (or DNA) samples to be provided by Users. Samples to be processed should be 1–10 μg of total RNA. Check total RNA integrity following isolation preferably using an Agilent Technologies 2100 Bioanalyzer with an RNA Integrity Number (RIN) value greater than 8. High quality RNA will show a 28S rRNA band at 4.5 kb that should be twice the intensity of the 18S rRNA band at 1.9 kb. Both kb determinations are relative to a RNA 6000 ladder. The mRNA will appear as a smear from 0.5–12 kb. For other arrangements please contact the platform directly.
The DNA samples to be processed should be 1–5 μg of highly purified DNA in a total volume of 50 μl of TE buffer, having an OD260/280 ratio of between 1.8 and 2, and should be as intact as possible.
Output – deliverables to User:
The sequence raw data output will be stored in electronic format and delivered to the Users in FASTQ and FASTA formats. Analysed data will be delivered in comma separated text files (*.csv) or Microsoft Excel sheets (*.xls).
