BP004261: Human IL-11R alpha Protein with the C-His Tag
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 Level: Less 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: It is recommended to reconstitute the lyophilized recombinant Human IL-11R alpha Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening.
