Growth Hormone Binding Protein
ovine (sheep), recombinant, E. coli
For in vitro use only!
Shipping: shipped at ambient temperature
Storage Conditions: store at -20 °C
avoid freeze/thaw cycles
Shelf Life: 12 months
Molecular Weight: 22 kDa
Accession number: P67930
Accession number: P67930
Purity: > 95 % (SDS-PAGE, RP-HPLC)
Form: lyophilized (GH was lyophilized from a 1 mg/ml solution with 0.0045 mM NaHCO3)
Solubility: It is recommended to reconstitute the lyophilized GH in sterile bidest H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
The Growth Hormone (GH) is a polypeptide that is secreted by the adenohypophysis. Growth hormone, also known as somatotropin, stimulates mitosis, cell differentiation and cell growth. Species-specific growth hormones have been synthesized. GH augments the cytolytic activity of T-cells, antibody synthesis, and granulocyte differentiation induced by GM-CSF. GH also enhances production of TNF-alpha, generation of superoxide anions from peritoneal macrophages, and natural killer activity. Recombinant Ovine Growth Hormone produced in E. coli is a single, non-glycosylated polypeptide chain containing 200 amino acids and having a molecular mass of 22.015 kDa. Recombinant Ovine GH is purified by proprietary chromatographic techniques.
Endotoxin: Less than 0.1 ng/μg (IEU/μg) of GH.
