Western blot analysis of Cingulin/CGN using anti-Cingulin/CGN antibody (A02373-1).
Electrophoresis was performed on a 8% SDS-PAGE gel at 80V (Stacking gel) / 120V (Resolving gel) for 2 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human 293T whole cell lysates,
Lane 2: human MCF-7 whole cell lysates,
Lane 3: human Jurkat whole cell lysates.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-Cingulin/CGN antigen affinity purified polyclonal antibody (A02373-1) at 1:1000 overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an ECL Plus Western Blotting Substrate (Catalog # AR1196-200) with Tanon 5200 system. A specific band was detected for Cingulin/CGN at approximately 150 kDa. The expected band size for Cingulin/CGN is at 136 kDa.

Background of CGN
Cingulin is a component of the cytoplasmic plaque of tight junction, and is localized on the cytoplasmic face of tight junctions of polarized epithelia and some endothelia. Cingulin is a homodimer, each subunit containing a globular "head" domain, a coiled-coil "rod" domain and a small globular "tail" region. Cingulin can interact interact with ZO-1, ZO-2, ZO-3, actin, and myosin. It probably plays a role in the formation and regulation of the tight junction paracellular permeability barrier.

1 Review For Anti-Cingulin/CGN Antibody
WB results showed that Cingulin/CGN (A02373-1) was downregulated in the rat colon model group and restored after Chinese medicine treatment, with the high-dose group showing the best effect, and the target bands were clear and specific.
| SKU | A02373-1 |
|---|---|
| Application | Western Blot |
| Sample | rat colon tissue |
| Sample Processing Description | Rat colon tissues were lysed in RIPA buffer containing PMSF (100:1) for 10 min, centrifuged at 12,000 rpm for 15 min, and the supernatant was mixed with 5× loading buffer, denatured at 100°C for 10 min, and then loaded onto SDS-PAGE. |
| Other Reagents | 5% non-fat milk |
| Primary Antibody | Cingulin/CGN Antibody |
| Primary Incubation | 1:1000, overnight at 4 ℃ |
| Secondary Antibody | HRP Conjugated AffiniPure Goat Anti-Rabbit IgG (H+L) (BA1054) |
| Secondary Incubation | 1:5000, 1 h in RT |
| Detection | Substrate: ECL substrate, Image system:ChemiDoc MP |
| Results Summary | The figure shows WB results of Cingulin/CGN and the internal control Actin in rat colon across different groups; expression was decreased in the model group and restored after Chinese medicine treatment, with the high-dose group showing the best effect, and the target bands were clear and specific, indicating satisfactory results. |
