  • Specification
  • Recommended Products
  • Cat.No.
  • CSC-CTK0216
  • Description
  • Recombinant Human Interleukin-2 (rHu IL-2) is a 15.5 kDa protein containing 134 amino acid residues. rHu IL-2 is a potent lymphoid cell growth factor, which exerts its biological activity primarily on T-cells.
  • Species
  • Human
  • Product Overview
  • Human IL2 expressed in E.coli
  • Molecular Mass
  • 15.5 kDa
  • Size
  • CAT# CSC-CTK0216-50 (50 μg); CAT# CSC-CTK0216-250 (250 μg)
  • Expression System
  • E.coli
  • Purity
  • Greater than 98% as determined by HPLC and SDS-PAGE analysis.
  • Activity
  • IL-2 is fully biologically active when compared to standards. The ED50 as determined by the dose-dependent stimulation of cell proliferation of murine CTLL-2 cells is less than 0.0645 ng/ml, corresponding to a specific activity of Greater than 1.5 x 10^7 units/mg.
  • Endotoxin Level
  • N/A
  • Formulation
  • Lyophilized protein with no additives. Lyophilized after extensive dialysis against sodium phosphate buffer (pH 7.5).
  • Reconstitution
  • Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted with 20 mM AcOH to a concentration of 0.1 - 1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
  • Storage & Stability
  • The lyophilized powder, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rHu IL-2 should be used immediately or stored long-term in undiluted working aliquots at -20°C. Avoid repeated freeze/thaw cycles. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
