Growth hormone receptor (GHR) is also known as somatotropin receptor, growth hormone-binding protein (GHBR), which belongs to the type I cytokine receptor family or Type 1 subfamily. GHR contains one fibronectin type-III domain. GHR / GHBR is expressed in various tissues with high expression in liver and skeletal muscle. The soluble form (GHBP) is produced by phorbol ester-promoted proteolytic cleavage at the cell surface (shedding) by ADAM17/TACE. GHR is receptor for pituitary gland growth hormone involved in regulating postnatal body growth. On ligand binding, couples to the JAK2/STAT5 pathway. The soluble form (GHBP) acts as a reservoir of growth hormone in plasma and may be a modulator/inhibitor of GH signaling.

Recombinant MABSol® Biotinylated Human GHR, His Tag, ultra sensitivity (primary amine labeling) (GHR-H8222) is expressed from human HEK293 cells. It contains AA Ala 27 - Tyr 264 (Accession # P10912-1). It is the biotinylated form of Human Growth Hormone R (GHR) Protein (GHR-H5222).
Predicted N-terminus: Ala 27

Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 29.6 kDa. The protein migrates as 40-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.
Biotin:Protein Ratio
The biotin to protein ratio is 4-5 as determined by the HABA assay.

Less than 1.0 EU per μg by the LAL method.

>90% as determined by SDS-PAGE.

Please refer to product data sheet.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Please see Certificate of Analysis for specific instructions.
