Source:
The recombinant Human IL-11R alpha Protein, (amino acids Ser24-Ala370) fused with a His tag at the C-terminus, was produced in HEK 293 cells.

Molecular Weight :
The recombinant Human IL-11R alpha protein with the His tag at the C-terminus has a predicted MW of 38.8 kDa. Due to glycosylation, the protein migrates to 50-55 kDa based on Tris-Bis PAGE result.

Activity:
The affinity constant of 1.86 nM as determined in SPR assay (Biacore T200).

Purity :
>95% by SEC-HPLC and SDS-PAGE under reducing conditions.

Endotoxin:
LevelLess than 1 EU per ug of protein as determined by LAL method.

Formulation :
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution:
