Our Anti-Connexin 43 Antibody primary antibody from PhosphoSolutions is rabbit polyclonal. It detects rat Connexin 43 and is antigen affinity purified from pooled serum. It is great for use in WB, IHC.
Western blot of rat cerebellar lysate showing specific immunolabeling of the ~43 kDa connexin43 protein.
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 Ser-368 by protein kinase C (Yogo et al., 2002; Bao et al., 2004a). Phosphorylation of Ser-368 by PKC induces a conformational change of connexin43 that results in a decrease in gap junction permeability (Bao et al., 2004b).

GJA1
43 kDa
Synthetic peptide corresponding to amino acid residues from the C-terminal region or rat connexin43, conjugated to keyhole limpet hemocyanin (KLH).
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.
Liquid
Prepared from rabbit serum by affinity purification on a column made with the C-terminal peptide used as antigen.
10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.
WB: 1:1000
IHC: 1:200
Unconjugated
Specific for endogenous levels of the ~43 kDa connexin43 protein.
Western blots performed on each lot.
