Western blot - Anti-Connexin 43 / GJA1 antibody [RM1071] - BSA and Azide free (AB314909)
This data was developed using ab314908, the same antibody clone in a different buffer formulation.
Western blot : Anti-GJA1 antibody [RM1071] (ab314908) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab314908 was shown to bind specifically to GJA1. A band was observed at 45 kDa in wild-type U-87 MG cell lysates with no signal observed at this size in GJA1 knockout cell line. To generate this image, wild-type and GJA1 knockout U-87 MG cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

What are recombinant multiclonals?
Recombinant multiclonals are a mixture of recombinant antibodies co-expressed from a library of heavy and light chains. They offer several advantages including:
- - The sensitivity of polyclonal antibodies by recognising multiple epitopes
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free batch production

Biological function summary
This protein facilitates electrical and chemical coupling between cells by forming intercellular channels. These channels arise from the assembly of six Connexin 43 subunits into hemichannels which dock with hemichannels on neighboring cells. This protein has a critical component in the cardiac and neural tissues where rapid communication is essential for proper function. Connexin 43 engages in complex assemblies with other connexins enhancing its role in synchronizing cell activities.
Pathways
Connexin 43 significantly influences signal transduction processes. It acts within the MAPK signaling pathway which impacts cellular responses such as growth and differentiation. Additionally this protein plays a role in calcium signaling a pathway important for muscle contraction and neurotransmitter release. Interacting proteins like Connexin 30 and Connexin 45 further regulate these pathways affecting the amplitude and duration of signaling.
