Specificity: Reacts strongly with Connexin-26, which has a predicted molecular weight of 26.5kD. Although the polyclonal anti-Cx26 antibody (feline. No. 71-0500) raised against the same sequence as this monoclonal anti-Cx26 antibody cross-reacts with Cx30, this monoclonal anti-Cx26 appears to exhibit minimal cross-reaction with Cx30 by western blotting. The degree of cross-reaction with Cx30 by IHC is uncertain, but may be influenced by fixation conditions. Rat, mouse and human. Reactivity of this antibody on Western blots has been confirmed by using extracts from mouse liver, mouse brain and rat brain.
