STAT2 phospho Tyr689 antibody (pAb) tested by dot blot analysis.

STAT2 phospho Tyr689 pAb tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of STAT2 phospho Tyr689 pAb for STAT2 phospho Tyr689. Phosphorylated peptides corresponding to the immunogen and related peptides were spotted onto PVDF and probed with the antibody at 1:10,000. The amount of peptide (picomoles) spotted is indicated next to each row.

STAT2 (signal transducer and activator of transcription 2) is a member of the STAT family of transcription factors. STATs undergo tyrosine and serine phosphorylation in response to growth factor or cytokine signaling. This phosphorylation results in dimerization and translocation of STAT proteins to the nucleus. STAT2 has been shown to be activated by IFNα and IFNβ, and to associate with the transcription factors p48 and p300.

Positive Control

Whole-cell extracts from cells treated with IFN-alpha (2500 units/ml for 30 minutes) can be used as positive control for STAT2 phospho Tyr689 antibody.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
