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. |
Description |
Interleukin-9 Rat Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 127 amino acids and having a molecular mass of 14.3kDa. The IL-9 is purified by proprietary chromatographic techniques. |
Source |
Escherichia Coli. |
Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation |
IL9 protein was lyophilized from a0.2um filtered concentrated solution in PBS, pH 7.4. |
Purity |
Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |

Biological Activity |
The ED50 as determined by a cell proliferation assay using murine TS1 cells is less than 10 ng/ml, corresponding to a specific activity of 1.0 x 105 IU/mg. |
Storage |
Lyophilized Interleukin-9 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IL9 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. |
