Anti-Proteasome Activator Subunit 4/PSME4 antibody (ab5620) at 1/2000 dilution + Mouse testis tissue lysate at 25 µg
Developed using the ECL technique.
Observed band size: 160,200 kDa why is the actual band size different from the predicted?
ICC/IF image of ab5620 stained HeLa 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 (ab5620, 5µg/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 1.43µM.
