Sheep GH Antagonist Protein

SKU: orb425698

Description

Recombinant of sheep GH Antagonist protein

Images & Validation

• Application Notes:
  Protein content: Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.63 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the DNAman computer analysis program of protein sequences

Key Properties

• Source: Escherichia Coli
• Biological Activity: GH G119R acts as antagonist using an in vitro bioassay in PDF-P1 3B9 cells stably transfected with rabbit GH receptors. It is capable of forming a 1:1 complex with the recombinant ovine growth hormone receptor extracellular domain (ECD) and binds to this ECD with affinity similar the the wild type oGH.
• Protein Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Phe-Pro-Ala
• Purity: Greater than 98.0% as determined by: (a) Analysis by RP-HPLC (b) Analysis by Gel Filtration. (c) Analysis by SDS-PAGE.

Storage & Handling

• Storage: Stability: Lyophilized GH G119R 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
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045M NaHCO3, pH 9.
• Expiration Date: 6 months from date of receipt.
• Disclaimer: For research use only
