IL-13 Variant Recombinant Protein

This IL - 13 analog shows a two fold increase, relative to wild type IL - 13, in bioactivity as measured by the in - vitro dose dependent activation of STAT6 and IL - 13 dependent gene induction in transfected A201.1 cells. This analog has also been shown to exhibit increased in vivo activity compared to wild type IL - 13, as measured by the induction of airway hyper - responsiveness.

The lyophilized IL-13 Variant recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted IL-13 Variant is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing IL-13 Variant recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
