分子别名（Synonym）:CD116,CDw116,CSF2R,CSF2RAX,CSF2RAY,CSF2RX,CSF2RY,GM-CSF-R-alpha,GMCSFR,GMR,SMDP4

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

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

分子量（Molecule Mass）：The recombinant human GM-CSFRα consists of 309 amino acids and has a predicted molecular mass of 36 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh GM-CSFRα is approximately 60-65 kDa due to glycosylation.

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 TF1 human erythroleukemic cells. The ED50 for this effect is 3-10 μg/mL in the presence of 0.4ng/mL GMCSF.

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain (Ser 2-Gly 320) of human GM-CSFRα (P15509-1) was expressed with the C-terminal fused polyhistidine tag.

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.
