  • Synonym
    IGF-I,IGF1A,somatomedin C,MGF
  • Source
    Human IGF-I, His Tag, premium grade(IG1-H5245) is expressed from human 293 cells (HEK293). It contains AA Gly 49 - Ala 118 (Accession # P05019-1).
    Predicted N-terminus: His
    It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.
  • Molecular Characterization
    IGF-I Structure

    This protein carries a polyhistidine tag at the N-terminus

    The protein has a calculated MW of 9.5 kDa. The protein migrates as 12 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.1 EU per μg by the LAL method.
  • Sterility
    The sterility testing was performed by membrane filtration method.
  • Mycoplasma
    Negative.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

 IGF-I SPR

Biotinylated Human IGF-I R, His,Avitag (Cat. No. IGR-H82E3) immobilized on CM5 Chip can bind Human IGF-I, His Tag, premium grade (Cat. No. IG1-H5245) with an affinity constant of 33.9 nM as determined in a SPR assay (Biacore 8K) (QC tested).

  • Background
    Insulin-like growth factor 1 (IGF-1 or IGF-I), also known as somatomedin C, is the dominant effector of growth hormone and is structurally homologous to proinsulin. Human IGF-1 is synthesized as two precursor isoforms with N- and alternate C‑terminal propeptides (1). These isoforms are differentially expressed by various tissues (1). The 7.6 kDa mature IGF‑1 is identical between isoforms and is generated by proteolytic removal of the N- and C‑terminal regions. Mature human IGF-1 shares 94% and 96% aa sequence identity with mouse and rat IGF-1, respectively (2), and exhibits cross-species activity. It shares 64% aa sequence identity with mature human IGF2. Circulating IGF-1 is produced by hepatocytes, while local IGF-1 is produced by many other tissues in which it has paracrine effects (1). IGF-1 induces the proliferation, migration, and differentiation of a wide variety of cell types during development and postnatally (3). IGF-1 regulates glucose and fatty acid metabolism, steroid hormone activity, and cartilage and bone metabolism (4‑7). It plays an important role in muscle regeneration and tumor progression (1, 8). IGF-1 binds IGF1R, IGF2R, and the insulin receptor, although its effects are mediated primarily by IGF1R (9). IGF-1 association with IGF binding proteins increases its plasma half‑life and modulates its interactions with receptors (10).
