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","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48647909245028,"sku":"EPT205","price":151.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_b3b8f03c-6559-48d2-9b6f-47ef27d1546e.jpg?v=1782704629","url":"https:\/\/www.genebiosystems.com\/en-fr\/products\/recombinant-human-ifn-alpha2b","provider":"GeneBio ","version":"1.0","type":"link"}
