The ED50 was determined by the dose dependent prolifiration of TF-1 cells and was found to be < 1ng/ml, corresponding to a specific activity of >1,000,000 units/mg. This analog has also been shown to exhibit increased in vivo activity compared to wild type IL-13.
Lyophilized from a 0.2um filtered concentrated solution in 1xPBS, pH 7.2, containing 5% trehalose.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 95% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Interleukin 13 Variant in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Interleukin-13 Variant although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IL13 Variant should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please avoid multiple freeze-thaw cycles.
Interleukin-13, NC30, ALRH, BHR1, P600, IL-13, MGC116786, MGC116788, MGC116789.
