Duolink®proximity ligation assay(PLA®)
allows for endogenous detection of protein interactions, post translational modifications, and protein expression levels at the single molecule level in fixed cells and tissue samples.

Visit our Duolink® PLA Resource Center
for information on how to run a Duolink®
experiment, applications, troubleshooting, and more.
To perform a complete Duolink®
in situ experiment you will need two primary antibodies (PLA, IHC, ICC or IF validated)
that recognize two target epitopes. Other necessary reagents include a pair of PLA probes from different species (one PLUS and one MINUS), detection reagents, wash buffers, and mounting medium. Note that the primary antibodies must come from the same species as the Duolink®
PLA probes. Analysis is carried out using HRP for brightfield detection.Specificity
Duolink® In Situ
Wash Buffer, Brightfield is used to wash specimen slides during Duolink®
In Situ Brightfield procedures. See datasheet for more details.Application Note
Two primary antibodies raised in different species are needed. Test your primary antibodies (IgG-class, mono- or polyclonal) in a standard immunofluorescence (IF), immunohistochemistry (IHC), or immunocytochemistry (ICC) assay to determine the optimal fixation, blocking, and titer conditions. Duolink® in situ
reagents are suitable for use on fixed cells, cytospin cells, cells grown on slide, formalin-fixed, paraffin embedded (FFPE), or tissue (fresh or frozen). No minimum number of cells is required.
