Product Name: Granulocyte Macrophage-Colony Stimulating Factor Human Recombinant, Sf9 Synonyms: CSF-2, MGI-1GM, GMCSF, Pluripoietin-alpha, Molgramostin, Sargramostim. Description: GM-CSF Human Recombinant produced in insect cells is a single, glycosylated, polypeptide chain containing 127 amino acids (18-144) and having a molecular mass of 14.6kDa. GM-CSF is fused to a C-terminal His -tag (6x His) and purified by proprietary chromatographic techniques. Uniprot Accesion Number: P04141 Amino Acid Sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Pro-Ala-Arg-Ser. Source: Insect Cells. Physical Appearance and Stability: Lyophilized Granulocyte Macrophage Colony Stimulating Factor although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution GMCSF should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. Formulation and Purity: The protein was lyophilized with PBS. Greater than 98.0% as determined by SDS-PAGE. Application: Solubility: It is recommended to reconstitute the lyophilized Granulocyte Macrophage Colony Stimulating Factor in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: The ED50 as determined by the dose-dependant stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line) is < 0.1 ng/ml, corresponding to a Specific Activity of 10, 000, 000IU/mg. Shipping Format and Condition: Lyophilized powder at room temperature. Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY. They may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
