Genedata Expressionist® Refiner Array

Microarray-based gene expression analysis

Refiner Array evaluates microarray data for quality issues, and flags problematic measurements. It provides a set of normalization algorithms and validated condensing methods to automately pre-process and summarize raw microarray data for subsequent statistical analysis. Standardized workflows increase reproducibility and support high-throughput processing of large experimental datasets.

Refiner Array monitors a variety of quality issues, such as:

  • Signal background due to insufficient washing
  • Array surface defects due to scratches
  • Signal intensity gradients due to temperature gradients during hybridization
  • Miscellaneous image distortions
  • Outliers due to incorrect scanner settings or an excessive amount of labeling
  • Technology specific parameters, such as 3‘/5‘ ratios for Affymetrix control genes, to judge RNA quality or monitor the amplification process.
