Cat#:RP-3459H;Product Name:Recombinant Human GM CSF Protein, HEK;Synonym:CSF-2, MGI-1GM, GM-CSF, Pluripoietin-alpha, Molgramostin, Sargramostim, MGC131935, MGC138897.;Description:GM-CSF Protein produced in HEK cells is a glycosylated monomer, having a molecular weight range of 15-36kDa due to glycosylation. The GM-CSF is purified by proprietary chromatographic techniques.;Source:HEK.;Purity:Greater than 95% as obsereved by SDS-PAGE.;Bioactivity:The specific activity was determined by the dose-dependent stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line) and is typically 0.4-2ng/ml.;Formulation:The GM-CSF was lyophilized from 1mg/ml in 1xPBS.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized GM-CSF in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized GM-CSF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GM-CSF 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.;
