Somatotropin Rainbow Trout (Oncorhynchus mykiss) Recombinant 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, 535 Dalton.
The Rainbow Trout (Oncorhynchus mykiss) Growth-Hormone Recombinant is purified by proprietary chromatographic techniques.
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.5% NaHCO3. Adjusted to pH-8.
It is recommended to reconstitute the lyophilized Growth-Hormone Rainbow Trout (Oncorhynchus mykiss) in 0.4% NaHCO3 or water adjusted to pH 8-9, not less than 100µg/ml and not more than 3mg/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 Growth-Hormone Rainbow Trout (Oncorhynchus mykiss) 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.
Greater than 95.0% as determined by:
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.
Amino acid sequence
Somatotropin Rainbow Trout (Oncorhynchus mykiss) Recombinant is biologically active in PDF-P1 3B9 cells stable transfected with rabbit GH receptors, though its activity is about 10 fold lower than that of human GH.
