Western Blotting
Western blot analysis of extracts from A431 cells, untreated or EGF-treated (100 ng/ml) for the indicated times, using Phospho-Stat3 (Ser727) Antibody (upper) or Stat3 Antibody #9132 (lower).
IF-IC
Confocal immunofluorescent analysis of HeLa cells, untreated (left), IL-6 treated (center) or IL-6 and phosphatase treated (right), labeled with Phospho-Stat3 (Ser727) Antibody (green) and Pan-Keratin (C11) Mouse mAb #4545 (red).
Chromatin IP
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 Hep G2 cells starved overnight and treated with IL-6 (100 ng/ml) for 30 minutes, and either 20 μl of Phospho-Stat3 (Ser727) Antibody or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human IRF-1 promoter primers, SimpleChIP® Human c-Fos Promoter Primers #4663, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

The Stat3 transcription factor is an important signaling molecule for many cytokines and growth factor receptors (1) and is required for murine fetal development (2). Stat3 is constitutively activated in a number of human tumors (3,4) and possesses oncogenic potential (5) and anti-apoptotic activities (3). Stat3 is activated by phosphorylation at Tyr705, which induces dimerization, nuclear translocation, and DNA binding (6,7). Transcriptional activation seems to be regulated by phosphorylation at Ser727 through the MAPK or mTOR pathways (8,9). Stat3 isoform expression appears to reflect biological function as the relative expression levels of Stat3α (86 kDa) and Stat3β (79 kDa) depend on cell type, ligand exposure, or cell maturation stage (10). It is notable that Stat3β lacks the serine phosphorylation site within the carboxy-terminal transcriptional activation domain (8).
