IL-19 and IL-20 are mainly produced by activated monocytes , IL-24 is produced by Th2 cells, monocytes, and melanocytic cells , and IL-22 and IL-26 are primarily produced by activated T cells. Like IL-10, these class II cytokines signal through heterodimeric receptors. Overexpression of IL-20 in transgenic mice causes neonatal death as well as skin abnormalities, including aberrant epidermal differentiation. IL-20 selectively enhances multipotential hematopoietic progenitors in vitro and in vivo. IL-20 is preferentially expressed in monocytes18 and induces STAT 3 activation through binding to 2 types of IL-20 receptor (R) complexes, either IL- 20R1/IL-20R2 or IL-22R1/IL- 20R2
Aliases- IL-20
- Recombinant Rat Interleukin-20 (IL20)
Formulation- Recombinant Rat Interleukin-20 was lyophilized from a 0.2 µm filtered PBS solution pH 7.5.
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at +2° to +8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
