General description
Activin A is a member of the TGF (transforming growth factor)-β family of proteins produced by many cell types throughout development. Mouse Activin A has 100% amino acid sequence identity to human, rat, porcine, bovine and feline proteins. Recombinant mouse Activin A is a nonglycosylated homodimer, containing two 117 amino acid chains, with a total molecular weight of 26.2 kDa.
Application
Activin A has been used:
- to induce differentiation of embryonic stem cells to pancreatic β cells
- in the induction of bone marrow-derived mesenchymal stem cells to insulin-producing cells
- to induce endoderm differentiation from human embryonic stem cells
- as a component of β cell induction medium.
Biochem/physiol Actions
Activins interact with Type I and Type II serine/threonine kinases to signal to SMAD proteins to regulate a variety of functions, including cell proliferation, differentiation, wound healing, apoptosis, metabolism, etc. Activin A is a homodimer of two β A chains and is not biologically active until the N terminal propeptide is cleaved from each chain. Activin A is involved in mesoderm formation and hematopoietic development.
Physical form
Recombinant mouse Activin A is lyophilized with 0.02% TFA.
Preparation Note
Centrifuge the vial prior to opening.
Reconstitution
Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water, which can then be further diluted to other aqueous solutions.
