Description générale
STAT proteins (Signal Transduction and Activators of Transcription) are latent cytoplasmic transcription factors that have the dual function of signal transduction and activation of transcription. STATs are activated by tyrosine phosphorylation in response to different ligands, after which they translocate to the cell nucleus. The N-terminal region is highly homologous among the STAT proteins and surrounds a completely conserved arginine residue. STATs are a part of the JAK-STAT signaling pathway – a major pathway of the immune system. All cytokines transduce critical signals through this pathway. STAT3 has been shown to be activated by IFN alpha but not IFN beta. The transcription factors associated with STAT3 are cJun and cyclic AMP responsive enhancer binding protein (CREB). Deletion of the STAT3 gene in knock out mice was lethal at the early embryonic stage.
Spécificité
Recognizes STAT3, Mr 92 kDa. Additional unknown bands may be detected.
Immunogène
Bacterially expressed GST fusion protein corresponding to a.a. 688-722 of human STAT 3 (RPESQEHPEADPGSAAPYLKTKFICVTPTTCSNTI). The immunizing sequence is identical in mouse and rat STAT3. The first 28 amino acids are identical to mouse STAT3B.
Epitope: a.a. 688-722
Application
Anti-STAT3 Antibody is a Rabbit Polyclonal Antibody for detection of STAT3 also known as Acute-phase response factor or DNA-binding protein APRF & has been validated in ChIP, EMSA, ICC, IP & WB.
Immunoprecipitation:
4 μg of a previous lot immunoprecipitated STAT3 from 500 μg of EGF-stimulated A431 RIPA lysate.
Gel Shift Assay:
An independent laboratory has reported that this antibody supershifts.
Immunocytochemistry:
10 μg/mL of a previous lot of this antibody showed positive immunostaining for STAT3 in A431 cells fixed with 95% ethanol, 5% acetic acid.
