Antigen/Purification: ExpandCollapse

The antigen is a peptide corresponding to amino acid residues from the C-terminal region of rat connexin43.

The antibody is prepared from pooled rabbit serum by affinity purification on a column made with the C-terminal peptide used as antigen.

Biological Significance: ExpandCollapse

Gap junctional intercellular communication is thought to play a key role in development and may also be involved in epilepsy (Aronica et al., 2001). Connexin43 forms gap-junctional channels and regulates the permeability of these gap junctions to small organic molecules. Permeability of connexin43 is known to be regulated by phosphorylation at Ser³⁶⁸ by protein kinase C (Yogo et al., 2002; Bao et al., 2004a). Phosphorylation of Ser³⁶⁸ by PKC induces a conformational change of connexin43 that results in a decrease in gap junction permeability (Bao et al., 2004b).

Storage

100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
