ab13507 staining ERp57 in the Human PC-3 prostate cancer cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with formaldehyde and blocked with 1% serum for 1 hour at 22°C. Samples were incubated with primary antibody (1/50 in 1% Donkey serum in PBST) for 1 hour at 22°C. An undiluted Alexa Fluor® 594-conjugated Donkey anti-rabbit IgG polyclonal was used as the secondary antibody.
ICC/IF image of ab13507 stained HeLa 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 (ab13507, 1/1000 dilution) 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.
