Elevated levels of Activin A in Human colorectal tumors and in postmenopausal women have been implicated in colorectal and breast cancers, respectively.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe biological activities of Activin A can be neutralized by inhibins and by the diffusible TGF-β antagonist, follistatin. Activin A binds to the two forms of activin receptor type I (Act RI-A and Act RI-B) and two forms of activin receptor type II (Act RII-A and Act RII-B).\n\u003c\/p\u003e\n\n\u003cp\u003e\nActivins are homodimers or heterodimers of different β subunits. They are produced as precursor proteins with an amino terminal propeptide that is cleaved to release the C-terminal bioactive ligand.\n\u003c\/p\u003e\n\n\u003cp\u003e\nRecombinant Human\/Murine\/Rat Activin A is a 26.0 kDa disulfide-linked homodimer of two βA chains, each containing 116 amino acid residues.\n\u003c\/p\u003e","brand":"Cell Culture Collective","offers":[{"title":"1 mg","offer_id":53075259392328,"sku":"HACTA-AF-1mg","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"2 µg","offer_id":53075271549256,"sku":"HACTA-AF-2ug","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"10 µg","offer_id":53075271582024,"sku":"HACTA-AF-10ug","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"50 µg","offer_id":53075271614792,"sku":"HACTA-AF-50ug","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"100 µg","offer_id":53075271647560,"sku":"HACTA-AF-100ug","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"250 µg","offer_id":53075271680328,"sku":"HACTA-AF-250ug","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"500 µg","offer_id":53075271713096,"sku":"HACTA-AF-500ug","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0906\/7570\/8232\/files\/Growth-Factor-Photo_da1d8f26-d3d1-487c-9b9e-21bd2c443880.png?v=1778492389","url":"https:\/\/cellbase.com\/nl\/products\/culturegro-human-activin-a-animal-free-recombinant-protein","provider":"Cellbase","version":"1.0","type":"link"}
