Specificity
This antibody recognises an epitope within the C-terminal (CT) region of signal transducer and activator of transcription 3 (STAT3), an 80-85 kDa member of the STAT protein family, which plays an important role in cell growth, survival differentiation and transformation, transducing signals from cytokine receptors to the nucleus. STAT3 is phosphorylated in response to cytokines and growth factors including interleukin-5, interleukin-6, epidermal growth factor and leukaemia inhibitory factor. It is expressed in the heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.
