Q:

We need dimeric human inhibin A.

A:
Thanks for your inquiry. Based on your information,we have #CSB-E08237h for you.This kit employs the competitive inhibition enzyme immunoassay technique. And it is directed to monomer.Theoretically,this kit detects all the materials that contains monomer.Simply speaking,this kit can detect dimeric human inhibin A. I will send you the kit manual by email.

  • 功能：
    Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Inhibins appear to oppose the functions of activins.
