Western blot analysis of CREB3L4 over-expressed 293 cell line, cotransfected with CREB3L4 Validated Chimera RNAi ( Cat # H00148327-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with CREB3L4 monoclonal antibody (M01), clone 3E3 (Cat # H00148327-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
Proximity Ligation Analysis of protein-protein interactions between CREB3 and CREB3L4. HeLa cells were stained with anti-CREB3 rabbit purified polyclonal 1:1200 and anti-CREB3L4 mouse monoclonal antibody 1:50. Each red dot represents the detection of protein-protein interaction complex, and nuclei were counterstained with DAPI (blue).
