Activin A Plant Recombinant Protein

Source : Nicotiana benthamiana plant 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. Activins are homodimers or heterodimers of the different subunit isoforms, part of the TGF 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.

Product Specifications

Product Name Alternative

Inhba||Inhibin beta A||FSH releasing protein.

Purification

Greater than 97.0% as determined by Analysis by SDS-PAGE.

Components

Lyophilized from 1mg/mL solution in Tris HCl 0.05M buffer at pH 7.4.

Storage Conditions

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.

Applications Notes

It is recommended to reconstitute the lyophilized Activin A in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
