Purity:
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

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.

Formulation:
Lyophilized from a concentrated (1mg/ml) solution containing 10mM Na₂PO₄, 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.

Activity:
The ED₅₀ as determined by the dose-dependant proliferation of human MO7e cells is < 0.5-0.7ng/ml.

Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
