Mature human IL-28A is an approximately 22-25 kDa protein that shares 66% amino acid (aa) sequence identity with mouse and rat IL-28A and shows cross-species activity. It shares 96% and 70% aa sequence identity with human IL-28B and IL-29, respectively. IL-28A promotes the Th1 polarization of dendritic cells in the airway and inhibits Th2 and Th17 mediated inflammation. IL-28A additionally exhibits anti-tumor activity, in part by enhancing IL-12 dependent anti-tumor CTL responses in vivo. In contrast, it is up-regulated in invasive bladder cancer where it promotes tumor cell migration.\u003c\/p\u003e\n\n\u003cp\u003eSequence: Val26-Val200\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.\u003cbr\u003e\nNormally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.\u003cbr\u003e\nPlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\n\n\u003cp\u003eReconstitution: Please refer to the printed manual for detailed information.\u003c\/p\u003e\n\n\u003cp\u003eEndotoxin: \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\n\n\u003cp\u003eCalculated MW: 20.6 kDa\u003c\/p\u003e\n\n\u003cp\u003eObserved MW: 20 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃.
