Affymetrix Expression Profiling Service

General Information

Affymetrix Inc. pioneered the field of oligonucleotide microarrays and has been the microarray ”gold standard” for fifteen years now. Affymetrix’ GeneChip™ technology applies a combination of photolithography and combinatorial chemistry to directly synthesise 25mer oligonucleotides on a glass surface. Up to 6.5 million different oligonucleotides are synthesised on a 1.7 cm² surface – an area as small as a thumbnail. Moreover, GeneChip™ technology excels with an outstandingly high degree of automation and reproducibility. More than twenty thousand peer-reviewed publications in high-ranking scientific journals are based on Affymetrix GeneChip™ data.

Service Range

Full Service: Customer sends total RNA or mRNA. ATLAS Biolabs takes over the complete processing procedure incl. sample labelling, array hybridisation, washing, staining, scanning and basic data analysis.

Core Service: Customer sends labelled cRNA/cDNA. ATLAS Biolabs performs array hybridisation, washing, staining, scanning and basic data analysis.

Small Sample Service: available for very limited amounts of total RNA (10–20 ng).

Data Analysis: is offered at various levels; starting from the simple determination of the transcriptional status of a gene (absent/present) via calculation of significantly up- and down-regulated genes, to more sophisticated analyses such as hierarchical clustering or principal component analysis.

Data Delivery

  • Timeline: 3–4 weeks after receipt of samples (for >50 samples, please inquire)
  • CD-ROM/DVD/external HDD sent to customer includes all original data (except from the dat file), as well as the results in XLS or TXT format
