Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, ChIP=Chromatin IP
Specificity / Sensitivity
Stat3 (79D7) Rabbit mAb detects endogenous levels of total Stat3 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a Stat3 fusion protein corresponding to the carboxy-terminal sequence of mouse Stat3 protein.
Western blot analysis of extracts from various cell lines using Stat3 (79D7) Rabbit mAb.
Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence® Control siRNA (Unconjugated) #6568 (-), SignalSilence® Stat3 siRNA I (+) or SignalSilence® Stat3 siRNA II #6582 (+), using Stat3 (79D7) Rabbit mAb #4904 and α-Tubulin (11H10) Rabbit mAb #2125. The Stat3 (79D7) Rabbit mAb confirms silencing of Stat3 expression, while the α-Tubulin (11H10) Rabbit mAb is used to control for loading and specificity of Stat3 siRNA.
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 Hep G2 cells treated with IL-6 (100 ng/ml) for 30 minutes, and either 20 μl of Stat3 (79D7) Rabbit mAb 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). Research studies have shown that 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).
