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 only differ in their sequences by one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.","brand":"ELK Biotechnology","offers":[{"title":"10ug","offer_id":50413925138712,"sku":"EPT239","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_565367de-dc84-4993-b699-308ee70fa741.jpg?v=1751164165","url":"https:\/\/danabiosci.com\/products\/ept239","provider":"Dana Bioscience","version":"1.0","type":"link"}
