Product Description	Recombinant Human IL-11R alpha Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ser24-Ala370.
Product Background	Abstract Interleukin-11 (IL-11) is a pleiotropic cytokine that belongs to gp130 family. IL-11 and its receptor, IL-11Ra, are expressed in human cancers,human cancer cells expressed a functional IL-11Ra subunit, which triggered signal transduction either by exogenous recombinant human IL-11 or by autocrine production of IL-11 in cells cultured under hypoxic conditions.
Product Category	Recombinant Protein / Antibody discovery

Protein	IL-11R alpha
Synonyms	IL-11R subunit alpha; IL-11R-alpha; IL-11RA; IL11RA
Accession	Q14626-1
Species	Human

Amino Acid Range	Ser24-Ala370
Molecular Weight	The protein has a predicted MW of 38.8 kDa. Due to glycosylation, the protein migrates to 50-55 kDa based on Bis-Tris PAGE result.
Activity	The affinity constant of 1.86 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-His
Expression 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	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
