Handling Advice: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.

Storage: 4 °C/-20 °C/-80 °C

Storage Comment: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Target Details

Target: STAT3 (Signal Transducer and Activator of Transcription 3 (Acute-Phase Response Factor) (STAT3))

Alternative Name: Signal Transducer and Activator of Transcription 3/STAT3

Background: Recombinant Human Signal Transducer and Activator of Transcription 3/STAT3 is produced with our E. coli expression system. The target protein is expressed with sequence (Met1-Asn175) of Human STAT3 fused with a 6His tag at the C-terminus.
Signal Transducer and Activator of Transcription 3 (STAT3) belongs to the transcription factor STAT family. STAT3 contains one SH2 domain and is a transcription factor expressed in most cell types. STAT3 is activated by multiple cytokines and growth factors including: IFN-a, IL-10, IL-6, IL-11, IL-12, IL-2, EGF etc. STAT3 functions as signal transducer and transcription activator that mediates cellular responses to interleukins, KITLG/SCF and other growth factors. In addition, STAT3 may also mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4.
