The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-α subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-α subtypes differ in their sequences by only one or two positions. Naturally occurring variants also include proteins that are truncated by 10 amino acids at the carboxyl-terminal end.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: \u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e: Measured in antiviral assay using A549 human lung cancer cells infected with vesicular stomatitisvirus (VSV) The ED\u003csub\u003e50\u003c\/sub\u003e for this effect is 5 ng\/mL.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e: Cys24-Glu188\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:  \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFormulation\u003c\/b\u003e: Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2.\u003cbr\u003eNormally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.\u003cbr\u003ePlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Please refer to the printed manual for detailed information.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEndotoxin\u003c\/b\u003e:  \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCalculated MW\u003c\/b\u003e: 19.4 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 17 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47982508179556,"sku":"PKSH033640","price":29300.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_728f20fd-71fb-4870-9b37-be3c3558c96b.jpg?v=1772388989","url":"https:\/\/www.genebiosystems.com\/en-jp\/products\/recombinant-human-ifna2b-ifna2-protein","provider":"GeneBio ","version":"1.0","type":"link"}
