Product Overview | |
| Name | IL 9 Human, Sf9 |
|---|---|
| Description | |
| Interleukin-9 Human Recombinant, Sf9 | |
| Accession (Primary) | P15248 |
| Synonyms | |
| P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine. | |
| Introduction | |
| Factor that is thought to be a regulator of hematopoiesis. It has been shown to enhance the growth of human mast cells and megakaryoblastic leukemic cells as well as murine helper t-cell clones. IL-9 is a glycoprotein with a molecular weight of 32-39 that is derived from T-cells, and maps to human chromosome 5. | |
| Source | |
| Escherichia Coli. | |
| Physical Appearance | |
| Sterile Filtered White lyophilized (freeze-dried) powder. | |
| Formulation | |
| Lyophilized from a concentrated (1mg/ml) solution 10mM Na 2 PO 4 , pH 7.5. | |
| Stability | |
| Lyophilized Interleukin-9 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL9 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. | |
| Purity | |
| Greater than 96.0% as determined by SDS-PAGE. | |

| Biological Activity | |
| The ED50 as determined by the dose-dependant stimulation of human MO7e cells is < 0.5 ng/ml, corresponding to a Specific Activity of 2,000,000IU/mg. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized Interleukin 9 in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Protein content | |
| Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 0.6 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a standard solution of IL-9 as a Reference Standard. | |
| Precautions | |
| IL 9 Human, Sf9 is for research use only and not for use in diagnostic or therapeutic procedures. | |
