Description

Activin A is a member of the TGF beta super family. It was originally identified and isolated because it stimulates the release of follicle-stimulating hormone (FSH). Activins are structurally related to inhibins, they share common beta subunits, but they exhibit opposite biological activities. Activins are homodimers of beta subunits and inhibins are heterodimers of an alpha subunit and a beta subunit. Since the initial discovery of Activin A, it has been shown to regulate cell differentiation, nerve cell survival, bone growth promotion, cell proliferation, and apoptosis. Activin A expression has been detected in prostate cancer, colon cancer and breast cancer. Because Activin A is able to inhibit cell proliferation by modulating the Rb pathway, it is thought to inhibit cancer development. This may not be the only mechanism by which activin may play a preventative role in cancer development. Activin has also been shown to increase the expression of a protein whose decreased expression is correlated with increased metastatic capacity. In addition, activin has an inhibitory effect on endothelial cell growth and can thereby block angiogenesis, preventing tumor growth and metastasis. The activin/inhibin nomenclature reflects the subunit composition of the proteins: activin A (βA - βA), activin B (βB - βB), activin AB (βA - βB), inhibin A (α - βA) and inhibin B (α - βB). At present, little is known about the contribution of the other β subunits to activin or inhibin formation and biology. At the amino acid sequence level, the mature human βA subunit is 100% identical to mouse βA, while the human and mouse α subunits share approximately 80% identity. Similarly to other TGF-β family members, activins exert their biological activities through binding to the heterodimeric complex composed of two membrane spanning serine-threonine kinases designated type I and type II. Two forms of activin receptor type I (Act RI-A and Act RI-B) and two forms of activin receptor type II (Act RII-A and Act RII-B) have been identified. Activin binds directly to Act RII, the complex then associates with Act RI and initiates signaling.

Biological Information

  • Clonality: Polyclonal
  • Host: Goat
  • Reactivity: Human, Rat
  • Conjugate: Antigen Affinity Purified

Handling

  • Quantity: 100 µg
  • Storage: The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Applications

  • In Situ Hybridization (ISH)
  • Mass Cytometry (CyTOF)
  • Neutralization (Neut)
  • Western Blotting (WB)
