Growth Hormone Ovine Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 200 amino acids and having a molecular mass of 22015 Dalton. The GH Ovine Recombinant is purified by proprietary chromatographic techniques.
GH is a member of the somatotropin/prolactin family of hormones which play an important role in growth control. The gene, along with four other related genes, is located at the growth hormone locus on chromosome 17 where they are interspersed in the same transcriptional orientation; an arrangement which is thoµght to have evolved by a series of gene duplications. The five genes share a remarkably high degree of sequence identity. Alternative splicing generates additional isoforms of each of the five growth hormones, leading to further diversity and potential for specialization. This particular family member is expressed in the pituitary but not in placental tissue as is the case for the other four genes in the growth hormone locus. Mutations in or deletions of the gene lead to growth hormone deficiency and short stature.
Sterile Filtered White lyophilized (freeze-dried) powder.
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
It is recommended to reconstitute the lyophilized Growth Hormone in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Growth Hormone althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GH Ovine 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.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ala-Phe-Pro-Ala.
Greater than 98.0% as determined by:(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE.
The activity as determined by the dose-dependant stimulation of the proliferation FDCP13B9 cells.
