Cat#: | RP-4088H |
Product Name: | Recombinant Human IL9 Protein |
Synonym: | P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine. |
Description: | Interleukin-9 Protein 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. |
Source: | E.coli |

Purity: | Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
Bioactivity: | The ED50 as determined by the dose-dependent stimulation of human MO7e cells is less than 0.2 ng/ml, corresponding to a Specific Activity of >5.0×106 IU/mg. |
Formulation: | IL-9 protein was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4. |
Stability: | Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃ |
Reconstitution: | 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. |
Storage: | 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. |
