IL-2 Protein

Description:
|IntroductionReco|1) it is not glycosylated; 2) the molecule has no N-terminal alanine; 3) the molecule has serine substituted for cysteine at amino acid position 125; 4) the aggregation state of molecule is likely to be different from that of native IL-2. |Reco|E. coli-derived.Reco|Met-Pro-Thr-Ser-Ser-Ser-Thr-Lys-Lys-Thr-Gln-Leu- Gln-Leu-Glu.Predicted molecular mass: 15,300 Daltons.The ED50 as determined by the dose-dependant stimulation of murine CTLL-2 cells is less than 0.1 ng/ml, corresponding to a Specific Activity of 1.0 x 10^7 IU/ mg.Purity: > 95% by SEC-HPLC and reducing SDS-|Formulation: Lyophilized from a 0.2 um filtered solution of 20 mM HAc-NaAc, 150 mM NaCl, pH 4.0.Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
