IGF-1 is a major hormonal mediator of statural growth. Under regular circumstances, GH binds to its receptor in the liver, and other tissues, and stimulates the synthesis/secretion of IGF-1. In target tissues, the Type 1 IGF receptor, that is homologous to the insulin receptor, is activated by IGF-1, leading to intracellular signaling which stimulates multiple processes leading to statural growth. IGF-1 metabolic actions are partly directed at stimulating the uptake of glucose, fatty acids, and amino acids so that metabolism supports growing tissues.

The LR3 is a long-term analog of human IGF-1, specifically designed and manufactured for mammalian cell culture to support large-scale manufacturing of recombinant biopharmaceuticals.
Recombinant Human LR3 Insulin Like Growth Factor-1 produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 83 amino acids and having a molecular mass of 9.1kDa.

Escherichia Coli.

Sterile Filtered White lyophilized powder.

Lyophilized from a 0.2µm filtered concentrated solution in 20mM PB, pH 7.2.

It is recommended to reconstitute the lyophilized LR3 IGF1 in sterile 18M-cm H₂O at a concentration of 100µg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized LR3 IGF1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution the LR3 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 .
Please prevent freeze-thaw cycles.

Greater than 97.0% as determined by -PAGE and HPLC.
