SIRS-Lab is a leading provider in gene expression services. Specialized in functional genomics and bioinformatics, we deliver complete microarray analyses with high regulatory compliant results. The all-inclusive service packs contain pre-experimental consultation, constant scientific assistance, and a final publication package. Customized study designs guarantee the highest possible level of relevance concerning your demands.
Key Facts
  • Sample preparation even with difficult samples (e.g. suboptimal RNA quality, brain stem nuclei) and low amount of starting material (e.g. dendritic cells, heart biopsies)
  • Access to complete Illumina® BeadChip portfolio (human, mouse, rat)
  • Customized data normalization and biostatistical data analyses
  • Competitive costs
  • Full data integrity
Workflow 
1. Pre-experimental consultation
  • Develop individual study design
  • Analyze costs Plan and realize experiments
  • Create individual time schedule
2. Biobank organization
  • Support sample collection (sample type, collection interval, etc.)

RNA PREPARATION

3. Micro-arrays and reagents selection
  • Select and order Illumina® BeadChip arrays
4. Sample preparation
  • Take-over of the sample – documentation and storage
  • Prepare RNA sample including quality test
  • RNA-source: cell culture, tissue, whole blood
  • RNA quality test: purity, concentration, degradation, etc.
Decide upon: Go vs. no go for further analysis depending on sample quality
  • Reverse transcription and amplification according to standard protocol provided by Ambion

5. Micro-array hybridization and scanning

  • Hybridize, wash, and scan micro-arrays

RESULT: Raw data package = expression level

BIOSTATISTICAL ANALYSIS

6. Primary biostatistical analysis
  • Evaluate biostatistical data (including normalization)
  • Apply methods of supervised / unsupervised learning
  • Apply R and bioconductor software packages

RESULT: Gene list package = investigation level
