STAT5A/B phospho Tyr694/Tyr699 antibody (pAb) tested by dot blot analysis.

STAT5A/B phospho Tyr694/Tyr699 rabbit pAb tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of STAT5A/B phospho Tyr694/Tyr699 rabbit pAb for STAT5A/B phospho Tyr694/699. Phosphorylated peptides corresponding to the immunogen and related peptides were spotted onto PVDF and probed with the antibody at 1:30,000. The amount of peptide (picomoles) spotted is indicated next to each row.

STAT5A/B (signal transducer and activator of transcription 5) is a member of the STAT family of transcription factors. STATs undergo serine and tyrosine phosphorylation in response to growth factor or cytokine signaling. This phosphorylation results in dimerization and translocation of STAT proteins to the nucleus. The STAT5 protein is expressed in most cell types and is activated by multiple cytokines and growth factors including: IFNα, IL-10, IL-6, IL-11, IL-12, IL-2, EGF, among others. Other members of the STAT family include STAT1α, STAT2, STAT3, STAT4, STAT5A, STAT5B and STAT6.

Positive Control

Active Motif's Nb2 nuclear extract (prolactin stimulated) (Catalog No. 36106) can be used as a positive control for STAT5A/B phospho Tyr694/Tyr699 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.
