| Purity | Greater than 99.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | Melanoma differentiation association like protein; MDA1; NG.1; ZMDA1; IL-10C; IL-19. | ||
| Amino Acid Sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Met-Leu-Arg-Arg-Cys. | ||
| Solubility | It is recommended to reconstitute the lyophilized Interleukin -19 in sterile 18MΩ-cm H2O at a concentration of 0.5mg/ml or less. | ||
| Stability | Lyophilized Interleukin-19 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution IL19 should be stored at 4°C between 2-7 days and for future use below -18°C .For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. | ||
| Biological Activity | The activity is determined by it's ability to activate STAT following receptor-ligand interaction. | ||
| Formulation | Lyophilized from a concentrated (1mg/ml) solution in water containing 10mM sodium citrate pH-5. | ||
IL19 is a cytokine that belongs to the IL10 cytokine subfamily. IL-19 is found to be preferentially expressed in monocytes. It can bind the IL20 receptor complex and lead to the activation of the signal transducer and activator of transcription 3 (STAT3). A similar cytokine in mouse is reported to up-regulate the expression of IL6 and TNF-alpha and induce apoptosis, which suggests a role of this cytokine in inflammatory responses. Alternatively spliced transcript variants encoding the distinct isoforms have been described.
The activity is determined by it's ability to activate STAT following receptor-ligand interaction.
