CNTFR,CNTF R alpha
Human CNTF R alpha, His Tag (CNR-H5225) is expressed from human 293 cells (HEK293). It contains AA Gln 23 - Pro 346 (Accession # AAH01492).
Predicted N-terminus: Gln 23
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 37.6 kDa. The protein migrates as 45-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Ciliary neurotrophic factor receptor subunit alpha (CNTFR or CNTFR-alpha) belongs to the type I cytokine receptor family and type 3 subfamily. CNTFR contains two fibronectin type-III domains and one Ig-like C2-type (immunoglobulin-like) domain. This receptor and its cognate ligand support the survival of neurons. This receptor is most closely related to the interleukin-6 receptor. This receptor possesses an unusual attachment to the cell membrane through a glycophosphatidylinositol linkage.
