Interleukin-9 Human Recombinant
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.
Description | Interleukin-9 Human Recombinant produced in E.Coli is a single, non-glycosylated single polypeptide chain containing 127 amino acids and having a molecular mass of 14,004 Dalton. The IL-9 is purified by proprietary chromatographic techniques. |
Synonyms | P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine. |
Source | Escherichia Coli. |

Purity | >96% as determined by SDS-PAGE and HPLC |
Formulation | Sterile Filtered White lyophilized (freeze-dried) powder. Lyophilized from a concentrated (1mg/ml) solution containing 10mM Na2PO4, pH 7.5. |
Stability | The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles. |
Biological Activity | The ED50 as determined by the dose-dependant proliferation of human MO7e cells is < 0.5-0.7ng/ml. |
Solubility | It is recommended to reconstitute the lyophilized Interleukin-9 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Usage | LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes. |
