Western Blot analysis of IL1B expression in transfected 293T cell line by IL1B polyclonal antibody. Lane 1: IL1B transfected lysate (30.7kD). Lane 2: Non-transfected lysate.

Proximity Ligation Analysis (PLA) of protein-protein interactions between IL1B and A2M. HeLa cells were stained with IL1B rabbit purified polyclonal 1:1200 and A2M mouse monoclonal antibody 1:50. Signals were detected (red), and nuclei were counterstained with DAPI (blue). Each red dot represents the detection of protein-protein interaction complex.
