- Overview
  - Insulin-Like Growth Factor-I Rabbit Recombinant produced in E. Coli is a single, non-glycosylated, polypeptide chain containing 71 amino acids and having a molecular mass of 7639 Dalton. The IGFs comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of growth hormone. Early studies showed that growth hormone 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, and somatomedin B. IGF-1 is a small protein secreted mostly but not exclusively by the liver and circulating in blood mostly as a complex with several IGF binding proteins. It has growth-regulating, insulin-like, and mitogenic functions and it is secreted in response to growth hormone stimulation.

    E. coli
    
    Type
    
    Recombinant Proteins
    
    Purification
    
    Greater than 98.0% as determined by: (a) Gel-filtration chromatography under non denaturing conditions. (b) Analysis by SDS-PAGE.
    
    Formulation
    
    The protein was lyophilized from a concentrated (0.5 mg/ml) solution with 0.02% NaHCO3.
    
    Storage
    
    Lyophilized Insulin-Like Growth Factor-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution 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.

- Applications
  - Application Description
    
    It is recommended to reconstitute the lyophilized rbIGF-I in sterile 0.4% NaHCO3 adjusted, not less than 100µg/ml, which can then be further diluted to other aqueous solutions. IGF-I is biologically active when compared to human IGF-1. The ED50, calculated by the dose -dependent proliferation of human MCF/7 cells is 5 to 25ng/ml in the cell culture mixture dependent on culture conditions. Its activity consists of 30-40 % compared to human IGF-1.
