Immunhistochemical analysis of agarose-embedded HEK-293T (Human epithelial cell line from embryonic kidney transformed with large T antigen) transfected with DDDDK-tagged human PD-L1 expression vector labeling DDDDK tag with ab205606 at 1/750 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Counterstained with hematoxylin.
Positive staining on HEK-293T cells transfected with DDDDK-tagged human PD-L1 expression vector (Panel A) is observed. No signal was detected on HEK-293T transfected with an empty vector (vector control), containing a C-terminal DDDDK tag (Panel B).
Heat mediated antigen retrieval was performed using EDTA buffer pH 9 before commencing with IHC staining protocol.

Confocal image showing positive staining for FLAG® on HEK-293T cells transfected with DDDDK-tagged PFKFB3 expression vector. Mouse monoclonal ANTI-FLAG® M2 antibody was used as a counterstain at 1/500 dilution, and AlexaFluor®647 Goat anti-mouse secondary (ab150115) was used as the secondary antibody only control at 1/500 dilution. The nucleus is counterstained with DAPI.
