The ED50 is <0.5 ng/mL as measured by murine BaF3 pro-B cells, corresponding to a specific activity of >2.0 × 106 units/mg. Appearance
Lyophilized powder. Formulation
Lyophilized after extensive dialysis against PBS, pH 7.2, with trehalose. Endotoxin Level
<1 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Human Interleukin-20 (rHuIL-20) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1% BSA. Storage & Stability
Lyophilized recombinant Human Interleukin-20 (rHuIL-20) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
Overexpression of Interleukin-20 (IL-20) in transgenic (TG) mice causes neonatal lethality with skin abnormalities including aberrant epidermal differentiation. Recombinant IL-20 protein stimulates a signal transduction pathway through STAT3 in a keratinocyte cell line, demonstrating a direct action of this ligand. An IL-20 receptor is identified as a heterodimer of two orphan class II cytokine receptor subunits[1]. |
