Protein Interaction Coupling (PICO) Technology

Actome’s pioneering PICO technology enables a highly versatile and sensitive approach to detect and quantify single proteins and protein interactions by translating protein status into DNA barcodes using digital PCR technology.


Actome’s PICO assay kits, in combination with our bioinformatic AMULATOR software, enable innovative applications in the fields of:

  • Utmost sensitive protein biomarker detection
  • Cellular pathway analysis
  • Disruptive cancer research applications
  • Innovative assays for pharmaceutical research


PICO products are based on a digital assay concept and utilize QIAGEN’s digital PCR (dPCR) technology for readout. This unique approach results in the following powerful features:

  • Homogeneous assay - no washing required
  • Digital detection of individual molecules
  • Simultaneous detection of proteins, post translational modifications and interactions
  • Measurement in the native biological environment
  • Small input sample volume (down to 1 - 10 µL)
  • Femtomolar sensitivity


Actome’s PICO technology empowers QIAGEN’s QIAcuity Digital PCR Systems to measure proteins and protein interactions. This enables novel assays and provides advantages over established technologies.

  • Higher sensitivity
  • More convenient workflow
  • Only one instrument required
  • Application note

  • Less input material required
  • Higher sensitivity
  • No target enrichment required

  • Multi-omics approaches targeting proteins and RNA
  • Detection of post-translational modifications
  • Absolute quantification of proteins
