分子别名（Synonym）:IDO,IDO-1,INDO,Indoleamine 2,3‑dioxygenase

种属（Species）：Human

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Supplied as sterile 50 mM NaAC, 100 mM Nacl, 20 % glycerol, pH 5.5.

分子量（Molecule Mass）：The recombinant human IDO1 consists of 403 amino acids and predicts a molecular mass of 45.2 KDa. It migrates as an approximately 46 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 oxidize L-tryptophan to N-formylk-ynurenine.

表达区间（Protein Construction）：A DNA sequence encoding the human IDO1 (NP_002155.1) (Ala2-Gly403) was expressed and purified with one additional amino acids (Gly) at the N-terminus.

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.
