Immunofluorescence staining of transfected HEK293F cells with CSB-MA000161M0m at 1:100, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor R-PE Goat Anti-Mouse IgG(H+L).

For western blotting, the blot was detected with CSB-MA000161M0m at 1:5000, and a HRP-conjugated Protein G antibody was used as the secondary antibody at 1:50000

Overlay histogram showing untransfected HEK293F cells (green line) or transfected HEK293F cells (red line) stained with CSB-MA000161M0m. The cells were fixed with 70% Ethylalcohol (18h) and then permeabilized with 0.3% Triton X-100 for 2 min. The cells were then incubated in 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1:200/1*106cells) for 1 h at 4°C. The secondary antibody used was FITC goat anti-mouse IgG(H+L) at 1/100 dilution for 30min at 4°C. Acquisition of >10,000 events was performed.
