Description：Recombinant Human IGF1 Protein is produced by E. coli expression system and the target gene encoding Gly49-Ala118 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of 300mM NaAc, pH 6.5.Gene Symbol：IGF1Alternative Names：IBP1; Insulin-like growth factor I; IGF-I; Mechano growth factor; MGF; Somatomedin-C Entrez Gene (Human)： 3479; SwissProt (Human)： P05019; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：GPETLCGAEL VDALQFVCGD RGFYFNKPTG YGSSSRRAPQ TGIVDECCFR SCDLRRLEMY CAPLKPAKSADirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
