• Description: Activins are homodimers or heterodimers of the various β subunit isoforms, belonging to the TGF-beta family. Mature Activin B has two chains of 123 amino acids residues (betaB-betaB). Activin exhibits a wide range of biological activities, including mesoderm induction, neural cell differentiation, bone remodelling, haematopoiesis, and reproductive physiology. Activins plays a key role in the production and regulation of hormones such as FSH, LH, GnRH and ACTH. Inhibins/Activins are protein that are formed by the dimerization of two subunits, i. e. an α (alpha) with either beta A (βA) - Inhibin A or beta B (βB) - Inhibin B. The subunits betaA and betaB can also form homodimers or heterodimers called Activin: Activin A (betaA -betaA), Activin B (betaB -betaB) and Activin AB (betaA -betaB). The Activin gene family comprises the additional, but poorly characterized members" Activin betaC (βC), beta D (βD) and beta E (βE). As with other members of the super-family, Activins 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, Activin type 1 receptors, ACVR1, ACVR1B, ACVR1C and Activin type 2 receptors, ACVR2A, ACVR2B.
• Form: Recombinant human Activin B is lyophilized from Tris HCl 0.05M buffer at pH 7.4.

• Endotoxin: < 0.04="" eu/μg="" protein="" (lal="">
• Purity: >97% by SDS-PAGE gel
• Storage: This lyophilized preparation is stable at 2-8o C for short term, long storage it should be kept at -20oC. Reconstituted protein should be stored in working aliquots at –20°C. Repeated freezing and thawing is not recommended.
• Reconstitution: Centrifuge vial before opening. Lyophilized protein should be reconstituted in water to a concentration of 50 ng/μl. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. At higher concentration the solubility may be reduced and multimers generated. Optimal concentration should be determined for specific application and cell lines.
