Chicken GH Antagonist Bioactive Protein Product Attributes

Product Type: Bioactive Protein
Recombinant GH Antagonist based upon sequence from Chicken
Host: QP10641 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of GH Antagonist was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Application Notes
Recommended Reconstitution Instructions: 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.
Bioactivity Data: 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.
Purity: Greater than 98.0% as determined by:(a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.
Concentration of Chicken GH Antagonist Protein: Protein quantitation was carried out by: UV spectroscopy at 280 nm using the absorbency value of 0.8 as the extinction coefficient for a 0.1% (1 mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
Endotoxin Levels:
Buffer: The protein was lyophilized from a concentrated (1 mg/ml) solution with 0.3% NaHCO3 pH 8.
Storage Conditions: 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.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
