85-1452-95　［取扱停止］STAT 1, Recombinant, Human (Signal Transducer and Activator of Transcription 1) 2ug　S7969-03H

特徴

• Recombinant Human STAT1 produced in E.Coli is a non-glycosylated polypeptide chain having a molecular mass of 90kD. Recombinant STAT1 is purified by proprietary chromatographic techniques. This protein is the full-length form of the protein with An amino-terminal His-tag.
• Unit Definition:Recombinant human STAT1 is phosphorylatable in vitro, using either immunoprecipitated JAK1 or JAK2, or whole cell extracts derived from interferon- -stimulated HEK 293 cells. This phosphorylation can be monitored by Western blot analysis using phosphorylation site specific antibody directed to STAT [pY701], in conjunction with chemiluminescence detection methods. Optimization of the cell stimulation protocol, cell lysis procedure, and reaction conditions may be required for each specific application.
• Storage:Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. Please avoid freeze-thaw cycles.
