{"product_id":"nsj-f54580-0-4ml","title":"Inhibin beta B chain Antibody \/ INHBB, 0.4 ml","description":"\u003cp\u003eThe inhibin beta B subunit joins the alpha subunit to form a pituitary FSH secretion inhibitor. Inhibin has been shown to regulate gonadal stromal cell proliferation negatively and to have tumour-suppressor activity. In addition, serum levels of inhibin have been shown to reflect the size of granulosa-cell tumors and can therefore be used as a marker for primary as well as recurrent disease.  Because expression in gonadal and various extragonadal tissues may vary severalfold in a tissue-specific fashion, it is proposed that inhibin may be both a growth\/differentiation factor and a hormone. Furthermore, the beta B subunit forms a homodimer, activin B, and also joins with the beta A subunit to form a heterodimer, activin AB, both of which stimulate FSH secretion.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.4 ml","offer_id":51552503300376,"sku":"F54580-0.4ML","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_d54d6dd8-0c9f-41f0-876c-82f3633f15ac.jpg?v=1768356476","url":"https:\/\/danabiosci.com\/products\/nsj-f54580-0-4ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
