Rat IL-21R / Interleukin-21 Re

分子别名（Synonym）:IL21R 种属（Species）：Rat 表达系统（Expressed Host）：HEK293 Cells 制剂（Buffer）：Lyophilized from sterile PBS, pH 7.4 分子量（Molecule Mass）：The recombinant rat IL21R comprises 228 amino acids and predicts a molecular mass of 26.5 kDa. The apparent molecular mass of the recombinant protein is approximately 43-48 kDa in SDS-PAGE under reducing conditions due to glycosylation. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：Immobilized rat IL21R-His at 10 μg/ml (100 μl/well) can bind biotinylated rat IL21-His (Cat:R1424-802B), The EC50 of biotinylated rat IL21-His (Cat:R1424-802B) is 4.6-10.9 ng/ml. 表达区间（Protein Construction）：A DNA sequence encoding the rat IL21R (Q5EBB1) (Ser2-Pro236) was expressed, fused with a polyhistidine tag at the C-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.
