Technical Data


Recombinant protein


IL-19 belongs to the IL-10 family of regulatory cytokines, which includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26. Members of this family share partial homology in their amino acid sequences, but they are dissimilar in their biological functions. Preliminary data suggests that IL-19 is a proinflammatory cytokine, because it up-regulates IL-6 and TNF-α, and induces apoptosis through TNF-α. IL-19 signals through the type I IL-20R. Human and murine IL-19 share 71% amino acid sequence identity. Recombinant Human IL-19 is a 35.8 kDa homodimer of two 154 amino acid chains. In solution, IL-19 exists predominantly as a non-disulfide-linked dimer.

Biological Activity

Determined by its ability to activate STAT following receptor-ligand interaction.


Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).


Centrifuge the vial prior to opening. Reconstitute in 10 mM Sodium Citrate, pH 3.0 to a concentration of 0.1–1.0 mg/ml. Do not vortex. This solution can be stored at 2–8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.
