Description: IL-23 Human Recombinant produced in HEK cells is a 55kDa heterodimeric protein composed of 2 disulfide-linked subunits - 19kDa (p19) and 43 kDa (p40).

Protein Derived From: HEK.

Physical Appearance: IL-23 if supplied as a sterile filtered White lyophilized (freeze-dried) powder.

Purity: Greater than 95.0% as determined by analysis by SDS-PAGE.

Stability: Lyophilized Interleukin-23 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-23 should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.

Biological Activity: The activity, as determined by the dose dependent secretion of IL-17 in response to IL-23 using murine splenocytes, the ED50 is 1.9ng/ml.

Solubility: It is recommended to reconstitute the lyophilized IL23 in sterile 1xPBS containing 0.1% endotoxin-free recombinant HSA.
