分子别名（Synonym）:IL21

种属（Species）：Canine

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：The recombinant canine IL21 consists of 130 amino acids and has a calculated molecular mass of 15 kDa. In SDS-PAGE under reducing conditions, it migrates as an approximately 15KDa band as predicted.

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

生物活性(Activity)：Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells.

表达区间（Protein Construction）：A DNA sequence encoding the canine IL21 (Q6L7I9) (His 18-Ser 146) was expressed, with an initial Met 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.
