蛋白结构(Molecular Characterization)

IL-11 R alpha Structure

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 39.6 kDa. The protein migrates as 47-52 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

IL-11 R alpha BLI

Loaded Biotinylated Human IL-11, His,Avitag (Cat. No. IL1-H82E3) on SA Biosensor, can bind Human IL-11 R alpha, His Tag (Cat. No. ILR-H52H5) with an affinity constant of 27 nM as determined in BLI assay (ForteBio Octet Red96e) (QC tested).

Protocol

 

背景(Background)

Receptor for interleukin-11 (IL11). The receptor systems for IL6, LIF, OSM, CNTF, IL11 and CT1 can utilize IL6ST for initiating signal transmission. The IL11/IL11RA/IL6ST complex may be involved in the control of proliferation and/or differentiation of skeletogenic progenitor or other mesenchymal cells (Probable). Essential for the normal development of craniofacial bones and teeth. Restricts suture fusion and tooth number.Soluble form of IL11 receptor (sIL11RA) that acts as an agonist of IL11 activity. The IL11:sIL11RA complex binds to IL6ST/gp130 on cell surfaces and induces signaling also on cells that do not express membrane-bound IL11RA in a process called IL11 trans-signaling.
