Gilthead Seabream GH Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant GH based upon sequence from Gilthead Seabream
Host: QP10633 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
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized Growth-Hormone Gilthead Seabream 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: Binding assays of the 125I-labeled gilthead seabream GH to dolphin fish liver microsomal fraction resulted in high specific binding characterized by a Ka of 1.93 nM and a Bmax of 540 fmol/mg microsomal fraction protein. Recombinant gilthead seabream Growth Hormone, like ovine placental lactogen, exhibited growth-stimulating activity when applied orally to Sparus aurata larvae or intraperitoneally to juvenile fish.

Purity: Greater than 98.0% as determined by:(a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.
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 0.02% NaHCO3.
Storage Conditions: Lyophilized Growth-Hormone Gilthead Seabream 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.
