circRNA Microarray Service

IntegrateRNA provides a comprehensive circRNA microarray profiling service based on the latest microarray technology and most powerful platforms. Our one-stop solution ranges from RNA QC, amplification, sample labeling, array hybridization, image data processing to in-depth data analysis. IntegrateRNA has standard microarrays for all circRNAs of human, mouse and rat available in the circBase database. We are confident to ensure your satisfaction in a professional manner.

Circular RNA (circRNA) is a novel type of RNA that, unlike linear RNA, forms a covalently closed continuous loop. Most of these circRNAs are conserved across species, and often show tissue or developmental-stage-specific expression. Moreover, circRNAs have been shown to function as natural miRNA and protein sponges. These suggest that circRNA is a novel class of biomarkers and play a crucial role in disease regulation. Microarray is the best tool for circRNAs expression profiling, overcoming the low detection efficiency of RNA-seq, especially suitable for the assay of exosome, plasma samples.

Workflow of Our Service

  • Total RNA isolation
  • RNA quality control
  • Linear RNA and rRNA removal (RNase R treatment)
  • Labeling, hybridization, washing, and scanning
  • Data extraction, analysis and summarization
