Monoclonal antibody MAB3069 was produced by the immunization of BALB/c mice with isolated rat junctional complexes, prepared by the method of Stevenson and Goodenough (1988). Epitope mapping, hydropathy plotting, and topological studies suggest that this antibody is very likely directed against an epitope located between residues 95-125 in the central cytoplasmic loop of rat Cx32.


Anti-Connexin 32 Antibody, clone M12.13 detects level of Connexin 32 & has been published & validated for use in WB, IH.

Immunohistochemistry: acetone or unfixed tissues recommended. Epitope is internal, paraffin sections are untested.

Works with lightly formaldehyde-fixed tissue.

Western blot: Detects a 27 kDa Connexin 32 polypeptide in blots of rat hepatocyte gap junctions and an additional 47 kDa band corresponding to aggregates.

Optimal working dilutions must be determined by end user.
