Duolink® PLA Technology

Proximity ligation assay (PLA) to detect protein interaction

Comprehensive Protein Analysis with Duolink® PLA Products

Detect, quantify and determine cell localization of protein interactions and their modifications in a single experiment. With signal amplification up to 1000 times, Duolink® proximity ligation assay (PLA) technology allows for protein detection under endogenous protein expression levels.

Two primary antibodies (PLA, IHC, ICC or IF validated) from different species that recognize two target epitopes must be selected before using Duolink®. Other necessary reagents to run a Duolink® experiment include a pair of PLA probes (one PLUS and one MINUS) with hosts corresponding to those of the primary antibodies, detection reagents, wash buffers, and a mounting medium. Use our Product Selection Guide to help you determine the best Duolink® products for your experiment.
