Gap junctions are intercellular protein pores. They enable cell-to-cell communication by allowing passage of ions and other small molecules. The subunits of gap junction channels are assembled from a family of proteins called connexins. Individual connexin molecules join to make hexameric hemichannels termed connexons; these structures dock to connexons on neighboring cells, forming gap junction pores. Connexin-43 is a member of the connexin family possessing four transmembrane regions, with cytoplasmic amino and carboxyl terminals. It undergoes rapid turnover in the cell and its monomers may reside in the ER/Golgi network, forming a reservoir available for assembly upon degradation of existing connexin-43 channels. In addition, it is believed that phosphorylation of connexin-43 plays a regulatory role both in the assembly of connexons and in gating activity at the gap junction.

This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
