Biological Activity
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.

Description
Interleukin-13 Variant Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 114 amino acids, with a substitution of Q for R at position 112 compared with the wild type IL-13, having a molecular mass of 12.5 kDa.
The IL-13 Variant is purified by proprietary chromatographic techniques.

Lyophilized from a 0.2?m filtered concentrated solution in 1xPBS, pH 7.2, containing 5% trehalose.

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

Purity
Greater than 95% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Interleukin 13 Variant in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized Interleukin-13 Variant although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution IL13 Variant should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
