General description

The 43 kDa connexin protein (connexin-43, Cx43) belongs to the a-type (group II) subfamily of connexin proteins. It is expressed in most tissues, even though the pattern of expression may differ in various cell types. For example, in the brain it is found in astrocytes, ependyma and leptomeninges but not in neurons, oligodendrocytes and pinealocytes; in the liver it is present in Ito cells but not hepatocytes. Gap junction protein levels change in response to disruption of tissue architecture. For instance, an increased expression of Cx43 was found in early stages of atherosclerosis.
Changes in the levels or types of connexin expressed in a given cell type have been found to correlate with tumor progression and metastasis. However, glioma cells transfected with the oncogene neu (c-erb-B2) have been shown to exhibit a major reduction in intercellular communication with no decrease in overall expression of Cx43.


Monoclonal Anti-Connexin-43 reacts specifically with connexin-43. Reactivity has been observed with human, bovine, hamster, rat, and mouse connexin-43.


Monoclonal Anti-Connexin-43 antibody may be used for the localization of connexin-43 using various immunochemical assays such as ELISA, immunocytochemistry, immunoblotting (43 kDa, and additional weaker bands), and immunohistochemistry (frozen and formalin-fixed, paraffin-embedded tissues).
