Product Name Growth Hormone Antagonist Chicken Recombinant
Synonyms GH1, GH, GHN, GH-N, hGH-N, Pituitary growth hormone, Growth hormone 1, Somatotropin.
Description Somatotropin Chicken Antagonist Recombinant mutein G119R produced in E.Coli is a single, non-glycosylated polypeptide chain containing 191 amino acids with an additional Ala at the N-terminus and having a molecular mass of 22.3 kDa. The Chicken Growth-Hormone Antagonist Recombinant is purified by proprietary chromatographic techniques.
Uniprot Accesion Number
Amino Acid SequenceThe sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Phe-Pro-Ala.
Source Escherichia Coli.
Physical Appearance and Stability Lyophilized Growth-Hormone Chicken antagonist although stable at room temperature for at least two weeks, should be stored desiccated below -18°C. Upon reconstitution and filter sterilization GH can be stored at 4°C, pH 9 for up to 4 weeks. For long term storage and more diluted solutions it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Formulation and Purity The protein was lyophilized from a concentrated (1mg/ml) solution with 0.3% NaHCO3 pH-8. Greater than 98.0% as determined by
Application
Solubility It is recommended to reconstitute the lyophilized Growth-Hormone Chicken antagonist in 0.4% NaHCO3 or water adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions, preferably in a presence of a carrier protein such as BSA or similar.
Biological Activity Recombinant Chicken Growth Hormone G119R mutant did not bind to ovine GHR-ECD and was devoid of any biological activity in FDC-P1 3B9 cells. However, in binding experiments that were carried out using chicken liver membranes, both ovine GH and chicken GH showed similar IC50 values in competition with 125I-ovine GH, while the IC50 of G119R mutein was 10-fold higher. These results emphasize the importance of species specificity and indicate the possibility of antagonistic activity of chGH G119R in homologous system.
Shipping Format and Condition Lyophilized powder at room temperature.
