All lanes : Anti-Raf1 antibody (ab18761) at 2 µg/mlLane 1 : HeLa (Human epithelial carcinoma cell line) Whole Cell Lysate Lane 2 : HepG2 (Human hepatocellular liver carcinoma cell line) Whole Cell Lysate Lane 3 : SW480 (Human colon adenocarcinoma cell line) Whole Cell Lysate Lysates/proteins at 10 µg per lane.SecondaryGoat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilutionObserved band size : 75 kDa (why is the actual band size different from the predicted?)
ab18761 stained MCF-7 cells. The cells were 100% methanol fixed (5 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 ab18761 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) 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.
