Introduction
The somatomedins, IGFs, comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of GH. Early studies showed that GH did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin. Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B.
Description
IGF1 Bovine Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 70 amino acids and having a molecular mass of 7.6kDa. IGF- I is purified by proprietary chromatographic techniques.
Source
Physical Appearance
Formulation
The IGF1 Bovine was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.0.
Solubility
It is recommended to reconstitute the lyophilized bovine IGF-1 in sterile 18MΩ-cm H2O at a concentration of 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized IGF-1 Bovine although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution bovine IGF1 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.
Purity
Greater than 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Amino acid sequence
Biological Activity
The biological activity was determined by the cell proliferation assay using serum free human MCF-7 cells in <2ng/ml, corresponding to a Specific Activity of >5.0 x 105IU/mg.
