Description: | IL-23 Protein produced in HEK cells is a 55kDa heterodimeric protein composed of 2 disulfide-linked subunits - 19kDa (p19) and 43 kDa (p40).? |
Source: | HEK. |
Purity: | Greater than 95.0% as determined by analysis by SDS-PAGE. |
Bioactivity: | The activity, as determined by the dose dependent secretion of h-IFN-g from human PBMC was found to be 2 to 20ng/ml ED50. |
Formulation: | IL-23 was lyophilized from a concentrated (480µg/ml) sterile solution containing 1x PBS. |
Stability: | Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃ |
Reconstitution: | It is recommended to reconstitute the lyophilized Interleukin-23 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Storage: | 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. |
