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.
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.
Biological Activity
The ED 50 as determined by the dose-dependent stimulation of human MO7e cells is less than 0.2 ng/ml, corresponding to a Specific Activity of >5.0×10 6 IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
IL-9 protein was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
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.
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 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
