SKU TP720012

Recombinant protein of human interleukin 2 (IL2), Pro22-Thr153

Product Data

• Species: Human
• Expression Host: E. coli
• Expression cDNA Clone or AA Sequence:
  Protein Sequence

  Pro22-Thr153
• Tag: Tag Free
• Predicted MW: 15.5 kDa
• Concentration: lot specific
• Purity: >95% as determined by SDS-PAGE and Coomassie blue staining
• Buffer: Lyophilized from a 0.2 um filtered solution of 10mM sodium citrate, pH 4.0.
• Bioactivity: ED50 is less than 0.1 ng/ml as determined by the dose-dependent stimulation of murine CTLL-2 cells. Specific Activity of 1.0 x 107 IU/ mg.
• Endotoxin: < 0.1 EU per µg protein as determined by LAL test
• Reconstitution Method: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. Dissolve the lyophilized protein in ddH2O. It is not recommended to reconstitute a concentration less than 100 µg/ml. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• 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.
• Stability: Stable for at least 6 months from date of receipt under proper storage and handling conditions.
• Shipping: Ambient

• Summary: This gene is a member of the interleukin 2 (IL2) cytokine subfamily which includes IL4, IL7, IL9, IL15, IL21, erythropoietin, and thrombopoietin. The protein encoded by this gene is a secreted cytokine produced by activated CD4+ and CD8+ T lymphocytes, that is important for the proliferation of T and B lymphocytes. The receptor of this cytokine (IL2R) is a heterotrimeric protein complex whose gamma chain is also shared by IL4 and IL7. The expression of this gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests an essential role of this gene in the immune response to antigenic stimuli.
