表达区间及表达系统(Source)

Human IL-3 R alpha, Llama IgG2b Fc Tag, low endotoxin (ILA-H5255) is expressed from human 293 cells (HEK293). It contains AA Thr 19 - Arg 305  (Accession # P26951-1).

Predicted N-terminus: Thr 19

蛋白结构(Molecular Characterization)

Unconjugated(Thr 19 - Arg 305 ) P26951-1

This protein carries a llama IgG2b Fc tag at the C-terminus.

The protein has a calculated MW of 60.9 kDa. The protein migrates as 45 kDa, 55 kDa and 80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 0.01 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

存储(Storage)

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

Human IL-3 R alpha, Llama IgG2b Fc Tag, low endotoxin (Cat. No. ILA-H5255) SDS-PAGE gel

Human IL-3 R alpha, Llama IgG2b Fc Tag, low endotoxin on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

背景(Background)

Interleukin 3 receptor alpha (low affinity) (IL3RA), also known as CD123 (Cluster of Differentiation 123) is a 70-kD glycoprotein member of the hematopoietin receptor superfamily. This protein associates with a beta subunit common to the receptors for IL-5 and granulocyte-macrophage colony-stimulating factor (GM-CSF) to form a high-affinity receptor for IL-3. The interleukin-3 receptor α chain (CD123) has been identified as a potential immunotherapeutic target because it is overexpressed in AML compared with normal hematopoietic stem cells.
