Synonyms Inhba, Inhibin beta A, FSH releasing protein.
Introduction Activins are homodimers or heterodimers of the differentβ subunit isoforms, part of the TGF -beta family. Mature Activin A has two 116 amino acids residues betaA subunits (bA-bA). Activin displays an extensive variety of biological activities, including mesoderm induction, neural cell differentiation, bone remodelling, haematopoiesis, and reproductive physiology. Activins takes part in the production and regulation of hormones such as FSH, LH, GnRH and ACTH. Cells that are identified to express Activin A include fibroblasts, endothelial cells, hepatocytes, vascular smooth muscle cells, macrophages, keratinocytes, osteoclasts, bone marrow monocytes, prostatic epithelium, neurons, chondrocytes, osteoblasts, Leydig cells, Sertoli cells, and ovarian granulosa cells.
Description Activin A human Recombinant produced in Nicotiana benthamiana plant is a disulfide-linked homodimers of two betaA chains, each containing 116 amino residues (molecular formula C600H911N173O174S13) and 6-His-tag at the N-terminal having the total molecular mass of 27.4kDa.
Source Nicotiana benthamiana plant
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation Lyophilized from 1mg/ml solution in Tris HCl 0.05M buffer at pH 7.4.
Solubility It is recommended to reconstitute the lyophilized Activin A in sterile 18 MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability Lyophilized Activin A although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Activin A should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Purity Greater than 97.0% as determined by Analysis by SDS-PAGE.
