Survey of Regulatory Elements is a massively parallel reporter assay. Some key differences compared to most other MPRAs are:

  • It uses genomic DNA fragments rather than synthetic oligonucleotides. This makes it possible to query larger DNA elements.
  • It can assay hundreds of millions of random DNA fragments, sufficient to obtain quantitative data for entire human genomes.
  • It can detect transcriptional activity of both promoters and enhancers.
  • It can be used to determine the impact of millions of human SNPs on the activity of regulatory elements.
