Tech Info / Data

11621 Activity Assay
11621 Purity Confirmation on SDS-PAGE

Recombinant human Activin A, expresed in engineered human cells, belongs to the TGF-beta superfamily. Activins are important for germ cell development and maturation, insulin secretion, nerve cell survival and the axial development of the embryo. Inhibins and activins regulate the secretion of follitropin by the pituitary gland and also contribute in regulating various functions such as hypothalmic, gonadal hormone secretion and erythroid differentiation.
