Western blot - Anti-Lamin B1 antibody - Nuclear Envelope Marker (ab16048)
Lane 1: Wild type HAP1 whole cell lysate (20 μg)
Lane 2: empty lane
Lane 3: KO HAP1 LMNB1 whole cell lysate (20 μg)
Lane 4: empty lane
Lanes 1 - 4: Merged signal (red and green). Green - ab16048 observed at 70 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab16048 was shown to specifically react with LMNB1 (Lamin B1) in wild type HAP1 cells. No band was observed when LMNB1 (Lamin B1) knockout samples were used. ab16048 LMNB1 (Lamin B1) and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 0.1 μg per mL and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Immunocytochemistry/ Immunofluorescence - Anti-Lamin B1 antibody - Nuclear Envelope Marker (ab16048)
ab16048 staining Lamin B1 in HepG2 cells. The cells were fixed with 4% paraformaldehyde (10 min), permeabilized with 0.1% PBS-Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab16048 at 0.1µg/ml and ab7291, Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control. Cells were then incubated with ab150081, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 488), pre-adsorbed at 1/1000 dilution (shown in green) and ab150120, Goat polyclonal Secondary Antibody to Mouse IgG - H&L (Alexa Fluor® 594), pre-adsorbed at 1/1000 dilution (shown in pseudocolour red). Nuclear DNA was labelled with DAPI (shown in blue).
Also suitable in cells fixed with 100% methanol (5 min).
Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Lamin B1 antibody - Nuclear Envelope Marker (ab16048)
IHC image of Lamin B1 staining in Human normal Liver formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab16048, 1μg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Lane 1: Wild-type HAP1 nuclear lysate (10 μg)
Lane 2: Lamin B1 knockout HAP1 nuclear lysate (10 μg)
Lanes 1 and 2: Green signal from target - ab16048 observed at 68 kDa. Red signal from loading control - ab10799 observed at 18 kDa.
ab16048 was shown to specifically react with lamin B1 in wild-type HAP1 cells. No band was observed knockout samples were used. Wild-type and lamin B1 knockout samples were subjected to SDS-PAGE. ab16048 and ab10799 (loading control to histone H3 at 0.1μg/mL) were both incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 h at room temperature before imaging.
