Lysates/proteins at 10 µg per lane.
All lanes : Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 22 kDa
Observed band size: 30 kDa why is the actual band size different from the predicted?
Additional bands at: 110 kDa, 120 kDa, 160 kDa, 37 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 20 minutes
The Interferon Beta protein sequence contains both a phosphorylation and a glycosylation site (Swissprot). Post-translation modifications could account for the migration of the band at a higher molecular weight than predicted.
ICC/IF image of ab85803 stained HepG2 cells. The cells were 4% PFA 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 (ab85803, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 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.
