Interleukin‑5 Receptor alpha (IL‑5 R alpha), also known as CD125, is a 60 kDa hematopoietin receptor that plays a dominant role in eosinophil biology.This is the receptor for interleukin-5. The alpha chain binds to IL5. IL-5R alpha/CD125 Protein, Human, Recombinant (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 38.7 kDa and the accession number is Q01344-1.

|
| Protein Purity |
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
|
| 分子量 |
The protein has a predicted MW of 38.7 kDa. Due to glycosylation, the protein migrates to 55-60 kDa based on Tris-Bis PAGE result.
|
| Endotoxin |
< 1 EU/μg by the LAL method.
|
| Formulation |
Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
|
| Reconstitution |
Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
|
| Stability & Storage |
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
|
| Shipping |
In general, Lyophilized powders are shipping with blue ice.
