Recombinant Human IGF-I Protein (RP01608)

Product name	Recombinant Human IGF-I Protein
Catalog No.	RP01608
Description	Recombinant Human IGF-I Protein is produced by Pichia expression system. The target protein is expressed with sequence (Gly49-Ala118) of human IGF-I (Accession #NP_001104755.1) fused with no additional amino acid.
Bio-Activity	Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. The ED₅₀ for this effect is typically 53.5-214.2 ng/mL.
Purity	> 95% by SDS-PAGE.
Endotoxin	< 0.1 EU/μg of the protein by LAL method.
Formulation	Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
Species	Human
Calculated MW	7.65 kDa

Synonym	IGF-1; IGF-I; IGF1A; IGFI; IGF?I; MGF; IGF1
Expression Host	Pichia
Tag	No tag
Swiss-Prot
Gene ID

Storage	Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Reconstitution	Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
