Product details:
Human Activin A ELISA Kit ab119568 is a sandwich ELISA to measure Human Activin A in serum, cell culture supernatant, tissue extracts, other biological fluids with a sensitivity of 12 pg/ml.
How the assay works
A Activin A specific mouse monoclonal antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells and incubated. A biotinylated detection monoclonal antibody from mouse, specific for Activin A is then added followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. TMB is then used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the Human Activin A amount of sample captured in plate.
Assay Specificity
Our ELISA kits are rigorously validated to ensure the highest level of consistency and reproducibility. Please check the protocol booklet for more details

Activin A also known by its gene name INHBA is a protein involved in various mechanical processes in the human body. This protein forms part of the transforming growth factor-beta (TGF-β) superfamily and has a molecular weight of approximately 25 kDa for its dimeric forms. Activin A is expressed in many tissues including the pituitary gland reproductive organs and placenta. Researchers often use techniques like the Activin A ELISA test kit to measure its concentration in biological samples.
Biological function summary
Activin A plays a significant role in regulating cell differentiation proliferation and apoptosis. As part of a complex Activin A interacts with specific receptors on cell surfaces initiating intracellular signaling cascades that influence these vital processes. It acts as a growth factor in the reproductive system influencing follicle-stimulating hormone (FSH) secretion and is important in embryonic development and wound healing.
Pathways
Activin A participates in pathways such as the TGF-β signaling pathway and the SMAD protein signaling pathway. Within these pathways it interacts with receptor proteins like type I and type II Activin receptors and downstream SMAD proteins. These interactions enable Activin A to regulate gene expression relevant to various cellular functions.
Altered Activin A levels have associations with conditions like cancer and fibrotic diseases. Its overexpression links to some cancer types including colorectal and prostate cancer where it influences tumor growth and metastasis. Moreover its interaction with proteins like myostatin may contribute to muscle wasting disorders. The dysregulation of these pathways highlights the significance of Activin A in pathophysiology.
