This Ab recognizes a protein of 27-32kDa, identified as Connexin 32, also called Gap junction protein beta 1. The connexin family of proteins forms hexameric complexes called connexons that facilitate movement of low molecular weight proteins between cells via gap junctions. Connexin proteins share a common topology of four transmembrane α-helical domains, two extracellular loops, a cytoplasmic loop and cytoplasmic N- and C-termini. Many of the key functional differences arise from specific amino-acid substitutions in the most highly conserved domains, the transmembrane and extracellular regions. Each of the approximately 20-connexin isoforms produces channels with distinct permeability and electrical and chemical sensitivities; therefore, one connexin usually cannot fully substitute for another.

Optimal dilution of the Connexin 32 antibody should be determined by the researcher.

A recombinant human protein was used as the immunogen for the Connexin 32 antibody.

Store the Connexin 32 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
