Description : | Inhibins are homodimers or heterodimers of the various β subunit isoforms, belonging to the TGFβfamily. Mature Inhibin Beta A has two 116 amino acids residues βA subunits (βA-βA). Inhibin exhibits a wide range of biological activities, including mesoderm induction, neural cell differentiation, bone remodelling, haematopoiesis, and reproductive physiology. Inhibin plays a key role in the production and regulation of hormones such as FSH, LH, GnRH and ACTH. Cells known to express Inhibin Beta A include fibroblasts, endothelial cells, hepatocytes, vascular smooth muscle cells, macrophages, keratinocytes, osteoclasts, bone marrow monocytes, prostatic epithelium, neurons, chondrocytes, osteoblasts, Leydigcells, Sertolicells, andovarian granulosa cells. As with other members of the super-family, Inhibins interact with two types of cell surface trans-membrane receptors (Types I and II) which have intrinsic serine/threonine kinase activities in their cytoplasmic domains, Inhibin type 1 receptors, ACVR1, ACVR1B, ACVR1C and Inhibin type 2 receptors, ACVR2A, ACVR2B. The biological activity of Inhibin Beta A can be neutralized by inhibins and by the diffusible TGF-B antagonist, Follistatin. |
Form : | Lyophilized from a Tris HCl 0.05M buffer at pH 7.4 |
Bio-activity : | Biological Activity:1. Effect of rh Activin A on mouse plasmacytoma cell line (MPC-11) cells proliferationThe biological activity of Activin A is measured by its ability to inhibit mouse plasmacytoma cell line (MPC-11) cells proliferation. Cell proliferation was measured by MTT method. ED50 ≤ 10ng/ml.2. Effect of rh Activin A on keratinocytes differentiation. |
Molecular Mass : | Several forms are observed with different predicted molecular masses such as monomer (13.7 kDa), dimmer ( 27.4 kDa) and multimeric forms. |

Endotoxin : | < 0.04="" eu/μg="" protein="" (lal=""> |
Purity : | >97% by SDS-PAGE gel |
Applications : | Cell culture. Western Blot. Immunogen. Dermocosmetics (Inhibin Beta A increases the expression of E-cadherin and improves the distribution of e-cadherin in cell-cell contact areas). |
Stability : | This lyophilized preparation is stable at 2-8oC for short term, long storage it should be kept at -20oC. |
Storage : | Reconstituted protein should be stored in working aliquots at –20°C. Repeated freezing and thawing is not recommended. |
Reconstitution : | Lyophilized protein should be reconstituted in water following instructions of batch Quality Control sheet. At higher concentrations the solubility may be reduced and multimers generated. Optimal concentration should be determined for specific application. |
