ICC/IF
Immunofluorescence analysis of A549 cells using CD22 antibody (green). Blue: DAPI fluorescent DNA dye. Red: Actin filaments have been labeled with Omnimabs® 594-Phalloidin.Cells are fixed in 4% paraformaldehyde at room temperature for 15 minutes. Then, they are permeabilized with a PBS (OM750003) solution containing 0.1% Triton X-100(OM750021) at room temperature for 15 minutes. Subsequently, the cells are blocked with 10% non - immune goat serum(OM760028) at room temperature for 1 hour.The cells are incubated overnight at 4°C with the primary antibody diluted 1:100 in PBS. The secondary antibody, Omnimabs® 488 Goat Ant-Rabbit IgG(H&L) (Green,OM643486), is diluted at a ratio of 1:400 and incubated with the cells for 1 hour.Nuclear DNA is labeled with DAPI (Blue,OM643160). F-actin is stained with Omnimabs® 594-Phalloidin (Red,OM750007) diluted 1:100 for 30 minutes.ELISA
