Anti-Occludin antibody images
Western blot - Anti-Occludin antibody (ab31721)
All lanes : Anti-Occludin antibody (ab31721) at 1 ?g/mlThis blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% Milk before being incubated with ab31721 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.
Immunocytochemistry/ Immunofluorescence - Occludin antibody (ab31721)
ICC/IF image of ab31721 stained Hek293 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab31721, 5?g/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor? 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor? 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43?M.
Western blot - Anti-Occludin antibody (ab31721)
Anti-Occludin antibody (ab31721) at 1 ?g/ml (blocked with 3% milk) + Kidney (Human) Tissue Lysate - adult normal tissue (ab30203) at 20 ?g
Secondary
Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
developed using the ECL technique
Performed under reducing conditions.
Predicted band size : 59 kDa
Observed band size : 63 kDa (why is the actual band size different from the predicted?)
Additional bands at : 26 kDa. We are unsure as to the identity of these extra bands.
Exposure time : 2 minutes
