Interferon-beta (IFN beta) is an extracellular protein mediator of host defense and homeostasis. IFN beta has well-established direct antiviral, antiproliferative, and immunomodulatory properties. Recombinant IFN beta is approved for the treatment of relapsing-remitting multiple sclerosis. The recombinant IFN beta protein has the theoretical potential to either treat or causes autoimmune neuromuscular disorders by altering the complicated and delicate balances within the immune system networks. It is the most widely prescribed disease-modifying therapy for multiple sclerosis (MS). Large-scale clinical trials have established the clinical efficacy of IFN beta in reducing relapses and slowing disease progression in relapsing-remitting MS. IFN beta therapy was shown to be comparably beneficial for opticospinal MS (OSMS) and conventional MS in Japanese. IFN beta is effective in reducing relapses in secondary progressive MS and may have a modest effect in slowing disability progression. In addition to the common antiviral activity, IFN beta also induces increased production of the p53 gene product which promotes apoptosis and thus has a therapeutic effect against certain cancers. The role of IFN-beta in bone metabolism could warrant its systematic evaluation as a potential adjunct to therapeutic regimens of osteolytic diseases. Furthermore, IFN beta might play a beneficial role in the development of chronic progressive CNS inflammation.\u003c\/p\u003e\n\n\u003cp\u003eSource: HEK293 cells\u003c\/p\u003e\n\n\u003cp\u003eTag: C-His\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.22 μm filtered solution of 25mM NaAc PH 5.0\u003c\/p\u003e\n\n\u003cp\u003eAntigen Sequence: MSYNLLGFLQRSSNFQCQKLLWQLNGRLEYCLKDRMNFDIPEEIKQLQQFQKEDAALTIYEMLQNIFAIFRQDSSSTGWNETIVENLLANVYHQINHLKTVLEEKLEKEDFTRGKLMSSLHLKRYYGRILHYLKAKEYSHCAWTIVRVEILRNFYFINRLTGYLRN\u003c\/p\u003e\n\n\u003cp\u003eEndotoxin: \u0026lt; 0.01 EU\/μg of the protein by LAL method\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"ABclonal","offers":[{"title":"20ug","offer_id":45198379057331,"sku":"RP02774-20","price":210.0,"currency_code":"CAD","in_stock":true},{"title":"50ug","offer_id":45198379090099,"sku":"RP02774-50","price":350.0,"currency_code":"CAD","in_stock":true},{"title":"100ug","offer_id":45198379122867,"sku":"RP02774-100","price":560.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_2f35b5f2-6abe-453b-bead-a6c7fbfebd26.png?v=1766961460","url":"https:\/\/afsbio.com\/products\/recombinant-human-ifn-beta-protein-rp02774","provider":"AFSBio Inc.","version":"1.0","type":"link"}
