Duolink® Proximity Ligation Assay

Inside every cell, there is a breakthrough waiting to be uncovered. The chance to change the origin of a human disease or discover the tell-tale signal of an irregular protein-protein interaction requires powerful investigative tools and a streamlined approach. Rely on Duolink® PLA to amplify protein signals by 1000x, allowing you to visually detect proteins and their interactions, all with a straightforward protocol.

Uncover the opportunities in your research with amplified performance and the benefits of Duolink® PLA technology:

  • Visualize protein interactions – both stable and transient
  • Detect endogenous proteins – no overexpression or genetic manipulation
  • High specificity – use of two antibodies/probes eliminates false positives
  • Single molecule sensitivity – rolling circle amplification makes proteins visible
  • No special equipment needed – standard immunofluorescence methods
  • Publication-ready results – compare image results from indirect methods (Co-IP/WB)

Duolink® PLA Products

  • Duolink® PLA Starter Kits contains all the necessary reagents you need to perform a fluorescent experiment and analyze up to 30 samples.
  • Duolink® Probemaker Kits enable the conjugation of a PLA oligo (PLUS or MINUS) to any antibody.
  • Duolink® PLA Multicolor Kits allow for multiplex applications.
  • Duolink® Fluorescent Kits enable use with four different fluorophores: green, orange, red, and far red.
  • Duolink® flowPLA Detection Kits enables flow cytometry applications using four colors: green, orange, red, and far red.
  • Duolink® PLA Brightfield Detection contains oligonucleotides labeled with horseradish peroxidase (HRP) allowing use with a light microscope.
