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. 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 A subunit forms a homodimer, activin A, and also joins with a beta B subunit to form a heterodimer, activin AB, both of which stimulate FSH secretion. Finally, it has been shown that the beta A subunit mRNA is identical to the erythroid differentiation factor subunit mRNA and that only one gene for this mRNA exists in the human genome.
The stated application concentrations are suggested starting points. Titration of the Inhibin beta A chain antibody may be required due to differences in protocols and secondary/substrate sensitivity.
A portion of amino acids 85-112 from the human protein was used as the immunogen for the Inhibin beta A chain antibody.
Aliquot the Inhibin beta A chain antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
