Duolinkproximity 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.Follow the Duolink In Situ Fluorescence Protocol to use this product. A set of short instructionsis also available.Visit our Duolink PLA Resource Center for information on how to run a Duolink experiment, applications, troubleshooting, and more.To perform a complete Duolink PLA 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 standard immunofluorescence assay equipment.SpecificityRed fluorescence detection reagents are often used with Texas Red® filter.Application NoteTwo 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.Let us do the work for you, learn more about our Custom Service Program to accelerate your Duolink projectsView full Duolink product list


This product is comprised of the following:• 5x Ligation - Contains oligonucleotides that hybridize to the PLA probes and all components needed for ligation except the Ligase• 1x Ligase (1 unit/µL)• 1x Polymerase (10 units/µL)5x Amplification Red - Contains all components needed for Rolling Circle Amplification (RCA) except the Polymerase. It also contains oligonucleotide probes labeled with a fluorophore that hybridize to the RCA product.See datasheet for more information.Not included in Detection kit:Primary antibodies, PLA probes, wash buffers, mounting medium

Features and Benefits

• No overexpression or genetic manipulation required• High specificity (fewer false positives)• Single molecule sensitivity due to rolling circle amplification• Relative quantification possible• No special equipment needed• Quicker and simpler than FRET• Increased accuracy compared to co-IP• Publication-ready results
