分子别名（Synonym）:IL-2,Interleukin-2,lymphokine,TCGF

种属（Species）：Human

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Lyophilized from sterile 50mM NaAc, pH 5.0

分子量（Molecule Mass）：The recombinant human IL-2 consists of 134 amino acids and has a calculated molecular mass of 15.5 kDa as predicted in SDS-PAGE under reducing conditions.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：Measured in a cell proliferation assay using CTLL2 mouse cytotoxic T cells.The ED50 for this effect is typically 1-5 ng/mL.

表达区间（Protein Construction）：A DNA sequence encoding the mature form of human IL-2 (P60568-1) (Ala 21-Thr 153) was expressed and purified, with an initial Met.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
