Product Specifications
Background Insulin like Growth Factors 2 (IGF-II) is a 7.48 kDa member of the Insulin-like Growth Factors with 67 amino acid residues. IGF-II is mainly expressed from placenta, extravillous trophoblasts, leydig cells, syncytiotrophoblasts, cytotrophoblasts, peritubular cells. IGF-II regulating fetoplacental development and tissue differentiation. In adults, IGF-II signaling involves glucose metabolism in adipose tissue, skeletal muscle and liver. It also has important implications for metabolic disorders and cancer.
Synonyms insulin-like growth factor-II, Somatamedin A
Uniprot ID P01344
Molecular Weight The protein has a calculated MW of 8.28 kDa. The protein migrates as 11 kDa under reducing condition (SDS-PAGE analysis).
Expression System Escherichia coli
Purity >98% as determined by SDS-PAGE.
Activity Measure by its ability to induce MCF-7 cells proliferation. The ED₅₀ for this effect is <3 ng/mL. The specific activity of recombinant human IGF-II is > 3x 10⁵ IU/mg.
Endotoxin Level <0.1 EU per 1 μg of the protein by the LAL method.

Protein Tag His Tag (N-term)
Form The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 8.0. If you have any concerns or special requirements, please confirm with us.
Application Cell Culture
Storage/Shipping
Stability & Storage Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
Shipping Blue Ice
Product Note
Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
