Immunoprecipitating Flag Tag in Transfected HEK-293 cell whole cell lysate
Lane 1: Mouse control IgG instead of CSB-MA000021M0m in Transfected HEK-293 cell whole cell lysate
Lane 2: CSB-MA000021M0m (1μl) + Transfected HEK-293 cell whole cell lysate (500μg)
Lane 3: Transfected HEK-293 cell whole cell lysate (20μg)
For western blotting, the blot was detected with CSB-MA000021M0m at 1:5000, and a HRP-conjugated Protein G antibody was used as the secondary antibody at 1:2000

Immunoprecipitating Flag Tag in 293F transfected whole cell lysate
Lane 1: Mouse control IgG instead of CSB-MA000021M0m in Flag Tag in 293F transfected whole cell lysate. For western blotting, a HRP-conjugated Protein G antibody was used as the secondary antibody (1/2000)
Lane 2: Company A (1μl), Company B (1μl), Company C (1μl), Company D (1μl), CSB-MA000021M0m (1μl) + Flag Tag in 293F transfected whole cell lysate (500μg)
Lane 3: Flag Tag in 293F transfected whole cell lysate (20μg)

Immunofluorescence staining of 293T cells transfected with Flag tag by CSB-MA000021M0m at 1:300, counter-stained with DAPI. The cells were fixed in 4% formaldehyde 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 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L). The image on the right is the 293T cells transfected without Flag tag.
