Supplementary Figure 1: STAT3 expression in HEK293 cells
From: Activating germline mutations in STAT3 cause early-onset multi-organ autoimmune disease
Western blot showing the expression of STAT3 protein in HEK293 cells transfected with STAT3 constructs. HEK293 cells were lysed, and protein extracts were probed with anti-STAT3 antibody. β-actin was used as a loading control. The experiment was repeated twice with similar results.
