Background
The IL-1 type II receptor (decoy RII) is a nonsignaling molecule the only established function of which is to capture IL-1 and prevent it from interacting with signaling receptor. The decoy RII is released in a regulated way from the cell surface.
Description
Recombinant Human IL-1R2/IL-1 RII/CD121b Protein is expressed from Expi293 with hFc tag at the C-terminal. It contains Phe14-Glu343.
Target
IL-1R2/IL-1 RII/CD121b
Species
Human
Gene/Protein ID
NP_004624.1
Exact Sequence
Phe14-Glu343
Molecular Weight
The protein has a predicted MW of 64.4 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on the Tris-Bis PAGE result.
Activity
Immobilized Human IL-1 Beta, His Tag at 5ug/ml (100ul/Well) on the plate. Dose response curve for Human IL-1R2, hFc Tag with the EC50 of 0.44ug/ml determined by ELISA (QC Test). The affinity constant of 0.88 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Tag
C-hFc
Express System
Expi293
Purity
> 95% as determined by Tris-Bis PAGE
Endotoxin
Less than 1EU per ug by the LAL method.
Formulation
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization.
