Incubation: Anti-CK4 Polyclonal Antibody, Unconjugated (TMAB-04954) 1: 200, overnight at 4°C, followed by conjugation to the secondary antibody and DAB staining
3. Blank control: A549.
Primary Antibody (green line): Rabbit Anti-Cytokeratin 4, membrane-bound isoform antibody (TMAB-04954)
Dilution: 1 μg /10^6 cells;
Isotype Control Antibody (orange line): Rabbit IgG.
Secondary Antibody: Goat anti-rabbit IgG-PE

Protocol
The cells were fixed with 4% PFA (10 min at room temperature) and then permeabilized with 90% ice-cold methanol for 20 min at-20℃. The cells were then incubated in 5% BSA to block non-specific protein-protein interactions for 30 min at at room temperature. Cells stained with Primary Antibody for 30 min at room temperature. The secondary antibody used for 40 min at room temperature. Acquisition of 20,000 events was performed.
