General description

Duolink® flowPLA Detection Kit contains detection oligonucleotides with a fluorophore (lex = 644 nm/lem = 669 nm).

Application

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

Duolink® flowPLA Detection Kits will enable sensitive detection of proteins, protein-protein interactions, and protein modifications within cell populations by flow cytometry. To perform a Duolink® flowPLA experiment, you will need fixed, suspended cells, two primary antibodies that specifically recognize your proteins of interest, a pair of PLA probes (one 100RXN PLUS and one 100RXN MINUS), wash buffer, and a Duolink® flowPLA Detection Kit. The flowPLA Kits are available with 5 different fluorophores: Violet, Red, Green, Orange, or FarRed. The flowPLA Kits contain all the necessary reagents to perform the amplification and detection of bound PLA probes by flow cytometry. Analysis is carried out using standard flow cytometry assay equipment. User must provide a fixed cell suspension, primary antibodies, and corresponding PLA Probes.

Follow the Duolink® PLA Flow Cytometry Protocol to use this product.

Visit our Duolink® PLA Flow Cytometry page on how to run a Duolink® flow experiment, applications, troubleshooting, and more.

Application Note

Primary antibodies 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. Flow validated antibodies are recommended.

Questions

1–3 of 3 Questions  
  1. Is it possible to just buy the 5x Detection Solution separately?

    1 answer
    1. Unfortunately, the kit components are not sold separately.

      Helpful?

  2. Can I use this kit in conjunction with staining for other markers? If so, would you recommend staining with the PLA kit first, followed by staining with other primary-conjugated antibodies?

    1 answer
    1. It is possible to counterstain after the Duolink in situ amplification. It is recommended to apply the counterstaining protocol after the completion of the Amplification step in section 7.3, step 5 of the Duolink In Situ Fluorescence User Manual.

      Please see the protocol below:
      https://www.sigmaaldrich.com/technical-documents/protocol/protein-biology/protein-and-nucleic-acid-interactions/duolink-counterstain

      Helpful?

  3. Hello, can I also dilute the 5 x detection stock in something else than high purity water? Maybe PBS?

    1 answer
    1. It is not recommended to use any other solvent to dilute the 5x detection stock due to the sensitivity of this reaction. The Duolink kits have been optimized for use under the conditions described. Deviation from the protocol may not offer the best results.
