Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IHC-P=Immunohistochemistry (Paraffin), IHC-F=Immunohistochemistry (Frozen), IF-F=Immunofluorescence (Frozen), IF-IC=Immunofluorescence (Immunocytochemistry)
Species predicted to react based on 100% sequence homology: Dog, Pig.
Specificity / Sensitivity
Connexin 43 Antibody detects endogenous levels of total connexin 43. This antibody does not cross-react with other connexins.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues of human connexin 43. Antibodies are purified by protein A and peptide affinity chromatography

Connexin 43 (Cx43) is a member of the large family of gap junction proteins. Connexins assemble as a hexamer and are transported to the plasma membrane to create a hemichannel that can associate with hemichannels on nearby cells to create cell-to-cell channels. Clusters of these channels assemble to make gap junctions. Gap junction communication is important in development and regulation of cell growth. Phosphorylation of Cx43 is important in regulating assembly and function of gap junctions (1,2). Ser368 of Cx43 is phosphorylated by protein kinase C (PKC) after activation by phorbol esters, which decreases cell-to-cell communication (3). Src can interact with and phosphorylate Cx43 to alter gap junction communication (4,5).
