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\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Elabscience Biotechnology","offers":[{"title":"50μg","offer_id":40757462761530,"sku":"PKSH033640-50","price":198.95,"currency_code":"USD","in_stock":true},{"title":"10μg","offer_id":40757462794298,"sku":"PKSH033640-10","price":73.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/elabscience_4030210c-bf0f-4000-b3be-af90678672e6.jpg?v=1737025713","url":"https:\/\/www.msesupplies.com\/en-de\/products\/recombinant-human-ifn-2b-ifna2-protein","provider":"MSE Supplies","version":"1.0","type":"link"}
