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.
Follow the Duolink® In Situ Fluorescence Protocol
to use this product. A set of short instructions
is 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.This starter kit supplies all other necessary reagents for 30 Duolink®
PLA reactions, which include a pair of PLA probes (Anti-Rabbit PLUS and Anti-Mouse MINUS), orange 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.Specificity
In Situ Orange Starter Kit Mouse/Rabbit requires one primary antibody from mouse and one primary antibody from rabbit. Orange fluorescence detection reagents are often used with Cyanine 3 filter. 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.
