Part of Bioactivity data

ACA-H421b-Cell-based assay
 Activin A CELL

Human Activin A, premium grade (Cat. No. ACA-H421b) inhibits the proliferation of MPC-11 cells. The specific activity of Human Activin A, premium grade is>5.00*10^2 IU/mg, which is calibrated against WHO Reference Reagent Activin A (Human, Recombinant) NIBSC code: 91/626 (QC tested).

ACA-H424x-Cell-based assay
 Activin A CELL

The bio-activity of Human Latent Activin A, His Tag (Cat. No. ACA-H424x) was determined by dose-dependent inhibition of the proliferation of MPC-11 cells. The EC50 for this effect is typically 47-66 ng/mL (Routinely tested).

 Activin A SPR

Human Activin RIIB, His Tag (Cat. No. ACB-H5226) immobilized on CM5 Chip can bind Human Activin A, premium grade (Cat. No. ACA-H421b) with an affinity constant of 0.216 nM as determined in a SPR assay (Biacore 8K) (Routinely tested).

 Activin A SPR

Biotinylated Human Activin RIIB Protein, His,Avitag (Cat. No. ACB-H82E3) immobilized on CM5 Chip can bind Human Latent Activin A, His Tag (Cat. No. ACA-H424x) with an affinity constant of 0.147 nM as determined in a SPR assay (Biacore 8K) (Routinely tested).

Synonym Name

Activin A,INHBA


Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. Activin enhances FSH biosynthesis and secretion, and participates in the regulation of the menstrual cycle. Many other functions have been found to be exerted by activin, including roles in cell proliferation, differentiation, apoptosis, metabolism, homeostasis, immune response, wound repair, and endocrine function. Conversely inhibin down regulates FSH synthesis and inhibits FSH secretion.Activins are nonglycosylated homodimers or heterodimers of various ¦Â subunits (¦ÂA, ¦ÂB, ¦ÂC, and ¦ÂE in mammals), while Inhibins are heterodimers of a unique ¦Á subunit and one of the ¦Â subunits. Activin A is a widely expressed homodimer of two ¦ÂA chains. The ¦ÂA subunit can also heterodimerize with a ¦ÂB or ¦ÂC subunit to form Activin AB and Activin AC, respectively. The 14 kDa mature human ¦ÂA chain shares 100% amino acid sequence identity with bovine, feline, mouse, porcine, and rat ¦ÂA.
