IGFs are mitogenic peptide growth factors that stimulate the proliferation and survival of a variety of cell types in vitro, including muscle, bone, and cartilage tissues.IGFs are produced primarily by the liver, although a variety of tissues produce IGFs at different times.IGFs belong to the insulin gene family, which also contains insulin and relaxin.IGFs are structurally and functionally similar to insulin but have a much much higher growth-promoting activity.The expression of IGF-II is influenced by placental prolactin, whereas the expression of IGF-I is regulated by growth hormone.Both IGF-I and IGF-II signal through the tyrosine kinase type I receptor (IGF-IR), but IGF-II can also signal through the IGF-II/mannose-6-phosphate receptor. Mature IGFs are produced by proteolytic processing of inactive precursor proteins that contain N-terminal and C-terminal prepeptide regions.
This product, Recombinant Human IGF-1, is supplied as a lyophilized powder with high activity, high purity and low endotoxin.

Storage
-25 ~ -15 ° C storage, valid for 1 year after receipt.
After re-solution, store at 2 ~8 °C, 30 days expiration date. After re-dissolving, store at -85~-65°C, 3 months expiration date.
Compounding Methods
Centrifuge before uncapping to bring contents to the bottom. Reconstitute in sterile distilled water to a concentration of 0.1-1.0 mg/mL, which can be diluted even further according to subsequent experiments; for long-term storage, it is recommended that carrier proteins (0.1% BSA) be added to the dilution buffer; dispense for a single experimental dose and freeze at -80°C to avoid repeated freezing and thawing.
Cautions
