Description
Recombinant Human Interleukin-22 is produced by our E.coli expression system and the target gene encoding Ala34-Ile179 is expressed.
Alias
Interleukin-22;IL-22;Cytokine Zcyto18;IL-10-related T-cell-derived-inducible factor;IL-TIF; IL22;ILTIF; ZCYTO18
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured by its ability to induce IL-10 secretion in COLO 205 human colorectal adenocarcinoma cells.The ED50 for this effect is less than 1 ng/ml.
Formulation
Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
Storage
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.
Warranty
For Research Use Only. Our recombinant proteins can not be used in diagnostic procedures.
