The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Phe-Pro-Ala.
GH G119R acts as antagonist using an in vitro bioassay in PDF-P1 3B9 cells stably transfected with rabbit GH receptors. It is capable of forming a 1:1 complex with the recombinant ovine growth hormone receptor extracellular domain (ECD) and binds to this ECD with affinity similar the the wild type oGH.
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
Sterile Filtered White lyophilized (freeze-dried) powder.
Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.66 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
Greater than 98.0% as determined by:
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized GH G119R in 0.4% NaHCO3 or water adjusted to pH 9, not less than 100ug/ml, which can then be further diluted to other aqueous solutions, preferably in a presence of a carrier protein such as BSA or similar.
Lyophilized GH G119R although stable at room temperature for at least two weeks, should be stored desiccated below -18oC. Upon reconstitution and filter sterilization GH can be stored at 4oC, 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.
