GH Ovine Protein (OPPA01626)

• Product Number: OPPA01626
• Name: GH Ovine Protein (OPPA01626)
• Protein Size (# AA): Recombinant amino acids
• Host: E. Coli
• Purity: Greater than 98.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
• Alias Symbols: GH1, GH, GHN, GH-N, hGH-N, Pituitary growth hormone, Growth hormone 1, Somatotropin, GH Ovine, Placental, Placental Ovine Growth Hormone Recombinant
• Peptide Sequence: The sequence of the first five N - terminal amino acids was determined and was found to be Ala - Thr - Phe - Pro - Ala.
• Product Format: The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3 adjusted to pH-9. Physical appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Description of Target: Recombinant Placental Ovine Growth Hormone
• Reconstitution and Storage: Lyophilized Ovine Placental Growth Hormone although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution GH Ovine Placental should be stored at 4C between 2-7 days and for future use below -18C. For long term storage it is recommended to add a carrier protein (0. 1% HSA or BSA). Please prevent freeze-thaw cycles.
• Additional Information: Solubility: It is recommended to reconstitute the lyophilized Growth Hormone in sterile 0.4% NaHCO3 pH-9 not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
• Additional Information: Biological Activity: 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).
• Additional Information: Protein Content: 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% (1mg/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.

• Additional Information: Product Introduction: 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 thought 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.
  Product Description: Placental Growth Hormone Ovine Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 191 amino acids and having a molecular mass of 21918 Dalton. The GH Ovine Recombinant is purified by proprietary chromatographic techniques.Placental Growth Hormone differs from pituitary Ovine Growth Hormone by two amino acids G9R/G63S. Placental Ovine Growth Hormone possesses higher biological activity as compared to pituitary Ovine GH.
