Connexin 43 (Cx43, Gap Junction Alpha 1 Protein, CxA-1) (MaxLight 490)

Recognizes rat Connexin 43 only when the serine at residue 368 is unphosphorylated. Does recognize Connexin 43 if it is phosphorylated at sites other than Ser368. In some cell types, crossreactivity with a ~70kD protein of unknown identity has been observed. This crossreactivity is likely due to a shared epitope. Species Crossreactivity: canine, human and mouse
