Application

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.

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.

Specificity
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.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. 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.

  6. Has Duolink been used for detection of changes in protein expression?

    The following reference cites the use of Duolink to detect changes in protein expression in Human. Raizer et al., Cancer 2010;116:5297-305

  7. How many reactions can be performed with the Duolink® In Situ Starter Kit?

    All of the starter kits for the Duolink product line will perform 30 reactions using 40 ul per reaction.    DUO92101 - Duolink® In Situ Red Starter Kit Mouse/Rabbit    DUO92102 - Duolink® In Situ Orange Starter Kit Mouse/Rabbit    DUO92103 - Duolink® In Situ Red Starter Kit Mouse/Goat    DUO92104 - Duolink® In Situ Orange Starter Kit Mouse/Goat    DUO92105 - Duolink® In Situ Red Starter Kit Goat/Rabbit    DUO92106 - Duolink® In Situ Orange Starter Kit Goat/Rabbit
