Data sheet
| Formulation | GMCSF was lyophilized after extensive dialysis against 1xPBS pH 7.4. |
| Solubility | It is recommended to reconstitute the lyophilized GMCSF in sterile 18M?-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity | Greater than 96.0% as determined by1. Analysis by RP-HPLC.2. Analysis by SDS-PAGE. |
| Description | GMCSF k9 Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 128 amino acids and having a molecular mass of 14.2 kDa. GM-CSF is purified by proprietary chromatographic techniques. |
| Protein Background | GMCSF is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13.GM-CSF stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes. |
| Expression host | Escherichia Coli. |
| Synonyms | CSF-2, MGI-1GM, GM-CSF, Pluripoietin-alpha, Molgramostin, Sargramostim, MGC131935, MGC138897. |
| Stability | Lyophilized GMCSF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GMCSF 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. |

| Physical Appearence | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Biological Activity | The ED50 as calculated by the dose-dependent stimulation of the proliferation of human TF1 erythroleukemic cells is typically 1-4 ng/ml. |
