IL-3 R Beta, CD131, Common beta Chain

Source

Human CD131 Protein, His Tag (CD1-H52H8) is expressed from human 293 cells (HEK293). It contains AA Trp 17 - Trp 443 (Accession # P32927-1).

Predicted N-terminus: Trp 17

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

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

The protein has a calculated MW of 50.6 kDa. The protein migrates as 55-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a dimer.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

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

バックグランド

CD131- the common β Subunit, is a member of the type 1 cytokine
receptor family. There are three major classes of heteroreceptor complexes, where the receptor complex utilises a common shared receptor subunit as a signal-transducing chain along with a cytokine specific subunit. These three classes include those which use gp130, those which use γc and those which use the common β subunit, βc(CD131). CD131 is shared by three of the “four-helical bundle” family of cytokines; IL-3, IL-5 and GM-CSF, and forms a receptor complex along with a cytokine specific α chain for each of these cytokines.Moreover, even though each of these cytokines have their own specific α subunit, the co-utilisation of CD131 suggests a common intra-cellular process of both unique and/or overlapping activities on expressing cells.
