Introduction

GHBP is a transmembrane receptor for GH. Binding of GH to the receptor leads to receptor dimerization and the activation of an intra- and intercellular signal transduction pathway leading to growth. A common alternate allele of this gene, called GHRd3, lacks exon three and has been well-characterized. Mutations in this gene have been associated with Laron syndrome, also known as the GH insensitivity syndrome , a disorder characterized by short stature. Other splice variants, including one encoding a soluble form of the protein , have been observed but have not been thoroughly characterized.

Description

GHBP Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 248 amino acids and having a molecular mass of 28107.01 Dalton.
GHR is purified by proprietary chromatographic techniques.

Source

Escherichia Coli.

Physical Appearance

Sterile Filtered White lyophilized powder.

Formulation

GHBP was lyophilized from a concentrated solution with 0.0045mM NaHCO3.

Solubility

It is recommended to reconstitute the lyophilized GHBP in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability

Lyophilized GHBP although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GHBP should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein .
Please prevent freeze-thaw cycles.

Purity

Greater than 98.0% as determined by:
Analysis by SEC-HPLC.
Analysis by -PAGE.

Biological Activity

GHBP is fully biologically active as evidenced by its ability of forming 2:1 complex with G.H.

Protein content

Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 2.6 as the extinction coefficient for a 0.1% solution. This value is calculated by the PC GENE computer analysis program of protein sequences .
2. Analysis by RP-HPLC, using a calibrated solution of GHBP as a Reference Standard.
