Growth Hormone Gilthead Seabream Recombinant
Product Name Growth Hormone Gilthead Seabream Recombinant
Synonyms GH1, GH, GHN, GH-N, hGH-N, Pituitary growth hormone, Growth hormone 1, Somatotropin.
Description Somatotropin Gilthead Seabream Recombinant Sparus Aurata produced in E.Coli is a single, non-glycosylated polypeptide chain containing 188 amino acids with an additional Ala at the N-terminus and having a molecular mass of 21.4 kDa. The Gilthead Seabream Growth-Hormone Recombinant is purified by proprietary chromatographic techniques.
Uniprot Accesion Number P29971
Amino Acid SequenceThe sequence of the first ten N-terminal amino acids of recombinant Gilthead Seabream growth hormone was determined and was found to be Ala-Gln-Pro-Ile-Thr-Asp-Gly-Gln-Arg-Leu.
Source Escherichia Coli.
Physical Appearance and Stability 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.
Formulation and Purity The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02% NaHCO3. Greater than 98.0% as determined by
Application
Solubility 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.
Biological Activity 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.
Shipping Format and Condition Lyophilized powder at room temperature.
