分子别名（Synonym）:IL-21,IL-22,IL-D110,IL-TIF,ILTIF,TIFa,TIFIL-23,zcyto18

种属（Species）：Human

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Lyophilized from sterile PBS, pH 8.0.

分子量（Molecule Mass）：The recombinant human IL22 consists of 147 amino acids and predicts a molecular mass of 16.9 KDa. It migrates as an approximately 15 KDa band 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 by its ability to induce IL-10 secretion in COLO 205 human colorectal adenocarcinoma cells. The ED50 for this effect is typically 0.1-0.5 ng/mL.

表达区间（Protein Construction）：A DNA sequence encoding human IL22(NP_065386.1) (Ala34-Ile179) was expressed with a N-terminal 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.
