IL-5R alpha/CD125 Protein, Human, Recombinant (His & Avi)

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) 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.

Description

Species	Human
Expression System	HEK293 Cells
Tag	C-His-Avi
Accession Number	Q01344-1
Synonyms	CD125, IL5RA, IL5R, IL-5 R alpha, MGC26560, IL-5Ra, HSIL5R3, IL-5 R α, CDw125CD125, IL-5 R α/CD125, IL-5R subunit alpha, IL-5R subunit α
Construction	Asp21-Glu335
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	38.7 kDa (predicted). Due to glycosylation, the protein migrates to 50-68 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.
Research Background	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.
