Description：Recombinant Human IGF2 Protein is produced by E. coli expression system and the target gene encoding Ala25-Glu91 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of 5mM Hac, pH 3.0.Gene Symbol：IGF2Alternative Names：Insulin-like growth factor II; IGF-II; Somatomedin-A Entrez Gene (Human)： 3481; SwissProt (Human)： P01344; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MFPAMPLSSL FVNAYRPSET LCGGELVDTL QFVCGDRGFY FSRPASRVSR RSRGIVEECC FRSCDLALLE TYCATPAKSEDirections 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.
