Certificate of Analysis and Data Sheet
Source:
E.Coli
Catalog No.
CYT-237
Background:
A polypeptide that is secreted by the adenohypophysis . Growth hormone, also known as somatotropin, stimulates mitosis, cell differentiation and cell growth. Species-specific growth hormones have been synthesized.
GH augments the cytolytic activity of T-cells, antibody synthesis, and granulocyte differentiation induced by GM-CSF . GH also enhances production of TNF-alpha , generation of superoxide anions from peritoneal macrophages, and natural killer activity.
Description :
Recombinant Ovine Growth Hormone produced in E.Coli is a single, non-glycosylated polypeptide chain containing 200 amino acids and having a molecular mass of 22015 Dalton.
Recombinant Ovine GH is purified by proprietary chromatographic techniques.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:
Ovine-GH was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
Solubility:
It is recommended to reconstitute the lyophilized Ovine-GH in sterile 18MΩ-cm
H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Stability:
Lyophilized Ovine-GH although stable at room temperature for 3 weeks, should be stored desiccated
below -18 C. Upon reconstitution Ovine-GH 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 avoid freeze-thaw cycles.
Purity:
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Anion-exchange FPLC.
(c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained.
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.
Dimers and aggregates:
Less than 1% as determined by silver-stained SDS-PAGE gel analysis.
Biological Activity:
ProSpec's Ovine Growth Hormone is fully biologically active when compared to standard.
The activity as determined by the dose-dependant stimulation of the proliferation FDCP13B9 cells.
Endotoxin:
Less than 0.1 ng/ug (IEU/ug) of roGH.
Protein content:
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.7 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 Ovine-GH as a Reference Standard.
Usage:
Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
