Ovine GH Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant GH based upon sequence from Ovine
Host: QP10634 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of GH 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 in sterile 0.4% NaHCO3 pH 9 not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: Ovine placental Grwoth Hormone is fully biologically active when compared to World Health Organization (WHO) reference standard using in vitro bioassay in PDF-P1 3B9 cells stably transfected with rabbit GH receptors. It is also capable of forming a 1:2 complex with the recombinant ovine growth hormone receptor extracellular domain (ECD).
Purity: Greater than 98.0% as determined by:(a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.
Concentration of Ovine GH Protein: Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.684 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). 2. Analysis by RP-HPLC, using a calibrated solution of GH as a Reference Standard.
Endotoxin Levels: < 1.0 EU per ug protein as determined by the LAL method.
Buffer: The protein was lyophilized from a concentrated (1 mg/ml) solution with 0.0045mM NaHCO3 adjusted to pH 9.
Storage Conditions: Lyophilized Ovine Placental Growth Hormone although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GH Ovine Placental should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage 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.
