- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.5 - 1.0 µg per ml (1:500 - 1:1000 dilution). For immunocytochemistry, a concentration of 0.5 μg/ml is recommended. For ChIP applications, the suggested dilution is 1:50 by volume. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
The STAT3 Phospho (Tyr705) antibody recognizes the regulatory tyrosine phosphorylation of human STAT3 protein and has been shown to be useful for Western blotting.
During PD testing, this clone failed to stain PFA-fixed cells that had been permeabilized with Triton X-100. We highly recommend permeabilizing cells with methanol.

- STAT3 is a 770 amino acid protein of 88 kD. It consists of a DNA binding domain, a SH2 domain, a regulatory tyrosine responsible for binding of SH2 domain, and a C-terminal transactivation domain.
- STAT3 is tyrosine phosphorylated by receptor kinases in response to a variety of cytokines and growth factors. It forms homo- or heterodimer with STAT1 when tyrosine is phosphorylated, and then translocates to nucleus, acting as a transcription regulator. It is also essential for the differentiation of TH17 cells, which is involved in autoimmune diseases.
