Abstract
Here we provide a SOP to outline the correct procedures to dual stain FFPE human tissue for, 1) pathological TDP-43 protein, along with 2) any other protein of interest, with the aim of visualising protein of interest histology in the context of TDP-43 pathology.
This protocol can be implemented for dual staining of any rabbit or mouse primary detection antibody (using the Novolink Polymer Detection System), with our TDP-43 RNA aptamer (biotinylated) as published in Acta Neuropathologica here https://link.springer.com/article/10.1007/s00401-024-02705-1 in Spence and Waldron et al., 2024.
The resulting dual stain will show brown chromogen (detecting the target of the primary antibody) with red chromogen (detecting TDP-43 pathology with our TDP-43 RNA aptamer.
