ProSpec-GHBP Human, His

Growth Hormone Receptor, Growth Hormone Binding Protein, Somatotropin Receptor GH Receptor, Serum Binding Protein, GHBP, GHIP.

Growth hormone receptor, also known as GHR is part of the cytokine receptor family.  GHR binds 2 receptor molecules and in this manner induces signal transduction through receptor dimerization. Furthermore, at high concentrations, growth hormone performs as an antagonist since there is a large difference in affinities at the respective binding sites. The antagonist action can be enhanced further by reducing binding in the low affinity binding site.

GHBP produced in Sf9 Insect cells is a single, glycosylated polypeptide chain containing 254 amino acids and having a molecular mass of 29.4kDa.
GHBP is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.

Sf9, Insect cells.

Sterile filtered colorless solution.

GHBP protein solution contains phosphate buffered saline and 10% glycerol.

Store at 4°C if entire vial will be used within 2-4 weeks.
