Immunofluorescence staining of GenCRISPRᵀᴹ SaCas9 Antibody (11C12) (GenScript, A01951-40) with SaCas9 in Hela cells.
HeLa cells transfected with J7RUA5 (SaCas9(BB)-2A-GFP) (colored green) were fixed with 4% Poly-Formaldehyde (5min) and then blocked in 3% BSA 30 min.
The cells were then incubated with GenCRISPRᵀᴹ SaCas9 Antibody (11C12) (GenScript, A01951-40) at 0.5 μg/ml mouse IgG at 0.5 μg/ml at room temperature for 2 h, followed by a further incubation at 37°C for 1 h with Goat Anti-Mouse IgG Antibody (H&L) [ifluor 555], pAb (GenScript) (colored red) at 5 μg/ml.
DAPI was used to stain the cell nuclei (colored blue) at a concentration of 0.2 μg/ml for 2 h at room temperature.
