Product Description	Recombinant Human IL-5 R alpha/CD125 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Asp21-Glu335.
Product 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.
Product Category	Recombinant Protein

Target	IL-5 R alpha/CD125
Synonyms	CD125; CDw125CD125; HSIL5R3; IL-5 R alpha; IL-5R subunit alpha; IL5R; IL5RA; IL-5Ra; MGC26560
Accession	Q01344-1
Species	Human
Biotinylated	no
Amino Acid Range	Asp21-Glu335
Molecular Weight	The protein has a predicted MW of 38.7 kDa. Due to glycosylation, the protein migrates to 50-68 kDa based on Bis-Tris PAGE result.
Activity	The affinity constant of 4.9nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-His-Avi
Express System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

	Human IL-5, His Tag immobilized on CM5 Chip can bind Human IL-5 R alpha, His Tag with an affinity constant of 4.9nM as determined in a SPR assay (Biacore T200).
	Human IL-5R alpha on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
	The purity of Human IL-5R alpha is greater than 95% as determined by SEC-HPLC.
