  • Specification
  • Product Description:
  • Mouse Il21 (Q9ES17) recombinant protein expressed in Escherichia coli.
  • Sequence:
  • MHKSSPQGPDRLLIRLRHLIDIVEQLKIYENDLDPELLSAPQDVKGHCEHAAFACFQKAKLKPSNPGNNKTFIIDLVAQLRRRLPARRGGKKQKHIAKCPSCDSYEKRTPKEFLERLKWLLQKMIHQHLS
  • Host:
  • Escherichia coli
  • Theoretical MW (kDa):
  • 15.1
  • Form:
  • Lyophilized
  • Preparation Method:
  • Escherichia coli expression system
  • Endotoxin Level:
  • < 0.1 EU/ug
  • Activity:
  • The activity is determined by the dose-dependent proliferation of human T cells co-stimulated with anti-CD3 epsilon . The expected ED50 for this effect is 2.5-7.5 ng/mL.
  • Storage Buffer:
  • Lyophilized with 20 mM NaHCO3, pH 8.5.
  • Storage Instruction:
  • Store at -20°C on dry atmosphere.
    After reconstitution with sterilized water, store at -20°C.
    Aliquot to avoid repeated freezing and thawing.
  • Note:
  • Result of activity analysis
  • Serial dilutions of mouse Il21 (starting at 100 ng/mL) or ConA (+ control) were added to primary mouse thymocytes cultured on an anti-cD3e coated plate. After 72 hours, total live thymoctyes were measured and the linear portion of the curve was us used to calculate the ED50.
