Cat#:RP-5224H;Product Name:Recombinant Human pro-IGF2 Protein;Synonym:Pro-Insulin Like Growth Factor-2, pro-IGF2.;Description:Pro-IGF2 Protein produced in HEK cells is a glycosylated monomer, contains 157 a.a. (24-180) having a total molecular weight of 25kDa. The Pro-IGF2 contains a C-terminal propeptide (E peptide) Arg92 to Lys180 and is purified by proprietary chromatographic techniques.;Source:HEK.;Purity:Greater than 90% as obsereved by SDS-PAGE.;Bioactivity:The specific activity was determined by the dose-dependent stimulation of the proliferation of MCF-7 cells (human breast cancer cell line) and is typically 2-8ng/ml.;Formulation:The Pro-IGF2 was lyophilized in 50mM Sodium Acetate pH 4.5 and 350mM NaCl.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Pro-IGF2 in sterile PBS containing 0.1% endotoxin-free recombinant HSA.;Storage:Lyophilized Pro-IGF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Pro-IGF2 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 (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
