Descrizione

General description

92 kDa

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. STAT 1, is activated by a number of different ligands, including IFNalpha, IFNgamma, EGF, PDGF and IL6. Phosphorylation of tyrosine 701 is required for STAT 1 dissociation from IFNGR1, homodimerization, and nuclear translocation. Tyrosine 701 phosphorylation impairment results in loss of STAT 1 functions.

Physical form

Immunoaffinity Chromatography

Immunoaffinity purified IgG in 0.02 M PBS containing 0.1% Sodium Azide + 50% Glycerol and 5 mg/mL BSA.

Preparation Note

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol-containing solutions to become frozen during storage.

Analysis Note

Control
Mouse 3T3-L1 adipocytes stimulated with leukemia inhibitory factor (LIF).

Routinely evaluated by immunoblot in RIPA lysates from CNTF-treated SK-N-MC cells.

Western Blot Analysis:
A 1:500-1:2000 dilution of this lot detected phosphorylated STAT1 in RIPA lysates from CNTF-treated SK-N-MC cells.
