All lanes : Anti-Lamin A + Lamin C antibody [4C11] (ab238303) at 1 µg/ml

Lane 1 : Wild-type HeLa cell lysate
Lane 2 : Lamin A + C knockout HeLa cell lysate

Lysates/proteins at 20 µg per lane.

Performed under reducing conditions.

Predicted band size: 74 kDa

This data was developed using the same antibody clone in a different buffer formulation (ab238303).

Lanes 1-2: Merged signal (red and green). Green - ab238303 observed at 74 kDa. Red - loading control ab181602 observed at 37 kDa.

 ab238303 Anti-Lamin A + C antibody [4C11] was shown to specifically react with Lamin A + C in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab261787 (knockout cell lysate ab256979) was used. Wild-type and Lamin A + C knockout samples were subjected to SDS-PAGE. ab238303 and Anti-GAPDH antibody[EPR16891] - Loading Control (ab181602) were incubated overnight at 4°C at 1 µg/ml and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye^® 800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye^® 680RD) preadsorbed (ab216777) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

 

 

ab238303 staining Lamin A+C (colored green) in wild-type HAP1 cells (top panel) and LMNA knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1% 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 with ab238303 at 1μg/ml and ab6046, Rabbit polyclonal to beta Tubulin - Loading Control, at 1/1000 dilution overnight at 4°C. Cells were then incubated with ab150077, Goat Anti-Mouse IgG H&L (Alexa Fluor^® 488) at 1/1000 dilution (shown in green) and ab150080, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor^® 594) at 1/1000 dilution (shown in pseudocolor red). Nuclear DNA was labeled with DAPI (shown in blue).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

This data was developed using the same antibody clone in a different buffer formulation containing PBS and sodium azide (ab238303).

ab238303 was shown to specifically react with Lamin A + C (LMNA) in wild type HAP1 cells. No band was observed when Lamin A + C (LMNA) knockout samples were used. Wild-type and Lamin A + C (LMNA) knockout samples were subjected to SDS-PAGE. ab238303 and ab181602 (Rabbit anti GAPDH loading control) were incubated overnight at 4°C at a 1ug/ml concentration 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 1/20000 dilution for 1 hour at room temperature before imaging.

IHC image of Lamin A + C staining in a section of formalin-fixed paraffin-embedded normal human skin* performed on a Leica BONDTM system using the standard protocol F.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab238303, 0.1 µg/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 hematoxylin and mounted with DPX.

The inset secondary-only control image is taken from an identical assay without primary antibody.

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.
