Product details:
The Rat IGF-1 Enzyme-Linked Immunosorbent Assay (ELISA) kit (ab213902) is designed for the quantitative measurement of Rat IGF-1 in cell culture supernatants, cell lysates, serum and plasma (heparin, EDTA).
The ELISA kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for IGF-1 has been pre-coated onto 96-well plates. Standards and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for IGF-1 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Rat IGF-1 amount of sample captured in plate.
Insulin-like growth factor 1 (IGF-1) that was once called somatomedin C, is a polypeptide protein hormone similar in molecular structure to insulin. It plays an important role in childhood growth and continues to have anabolic effects in adults. Human IGF1 is a single chain 70-amino acid polypeptide cross-linked by 3 disulfide bridges, with a calculated molecular mass of 7.6 kD. The IGF1 gene, mapped on 12q22-q24.1, contains 5 exons. Exons 1-4 encode the 195-amino acid precursor (IGF1B), and exons 1, 2, 3, and 5 encode the 153-residue peptide (IGF1A). The structure of IGF1 resembles that of IGF2. And the IGF1 and IGF2 genes have complex structures with multiple promoters. The expression of both genes is regulated at the levels of transcription, RNA processing, and translation. IGF-1 is produced primarily by the liver as an endocrine hormone as well as in target tissues in a paracrine/autocrine fashion. Moreover, approximately 98% of IGF-1 is always bound to one of 6 binding proteins (IGF-BP). Furthermore, IGF-1 is one of the most potent natural activators of the AKT signaling pathway, a stimulator of cell growth and multiplication and a potent inhibitor of programmed cell death.

The insulin-like growth factor 1 or IGF1 is a protein hormone that plays an important mechanical role in growth and development. Alternative names for IGF1 include somatomedin C. This protein has a mass of approximately 7.6 kDa and is mainly produced by the liver. IGF1 is expressed in a range of tissues including muscle bone and cartilage reflecting its importance in various physiological processes. Its production is stimulated by growth hormone and it acts in an autocrine and paracrine manner to exert its effects.
Biological function summary
IGF1 stimulates growth and proliferation of cells most notably impacting the development of the skeletal system and the regulation of apoptosis. It is not part of a larger protein complex but it interacts closely with IGF1 receptor to execute its functions. By binding to this receptor IGF1 activates intracellular signaling cascades that promote anabolic effects which include increased uptake of glucose and amino acids contributing to muscle and tissue growth.
Pathways
IGF1 operates within the PI3K-Akt and MAPK signaling pathways which are significant for cell survival and proliferation. Its interaction with proteins like IGF binding protein 3 (IGFBP3) modulates its availability and activity in the bloodstream. These pathways are critical for mediating the effects of growth hormone highlighting the role of IGF1 in systemic growth and metabolism regulation.
Alterations in IGF1 levels associate with growth abnormalities such as Laron syndrome and acromegaly. Laron syndrome results from the body's inability to use IGF1 properly due to receptor defects while acromegaly occurs from excessive IGF1 production often due to pituitary tumors. Furthermore aberrant IGF1 signaling connects to cancer development where it can drive tumor growth and metastasis. Drugs targeting IGF1 and its pathway components continue to be researched for therapeutic potential in these conditions.
