Application
This product can be applied to both the Duolink® In Situ Fluorescence Protocol and the Duolink® In Situ Brightfield Protocol depending on the detection reagents used.
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.HRP is also available for brightfield detection.
PLA probe anti-Goat reacts with whole molecule goat IgG and the light chains of other goat immunoglobulin?s. The PLA probe anti-Goat may cross-react with sheep antibodies, but has minimal cross reactivity with chicken, guinea pig, Syrian hamster, horse, human, mouse, rabbit, and rat serum proteins. A MINUS probe of a different species must be used simultaneously with this product. See our Product Selection Guide for more information.
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® PLA 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.

What epitope on the antibody is recognized by the Duolink PLA Probes?
The Duolink PLA Probes offered are donkey polyclonal antibodies directed to the whole molecule (heavy and light chains). They are affinity purified. The same polyclonal antibody is conjugated to the Plus and Minus Oligos. The Plus and Minus probes can be used together (to detect a single antibody) since they can recognize multiple sites. The anti-mouse IgG PLA labeled antibodies may cross-react with rat but this is not consistent. Do not use this product with rat antibodies. It is best to label anti-rat secondary antibodies with the Duolink Probemaker kit.The anti-goat IgG PLA labeled antibodies have cross-reactivity with sheep IgG and can be recommended for this application.
Has Duolink been used for detection of changes in protein expression?
