INHBA, 311-426aa, Human, His tag, E.coli

INHBA also known as inhibin beta A chain . The inhibin beta A 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 tumor-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. Recombinant human INHBA, fused to His-tag at N-terminus, was expressed in E.coli.
