Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-Lamin B1 antibody [EPR8985(B)] - Nuclear Loading Control (AB194109)

IHC image of Lamin B1 staining in a section of formalin-fixed paraffin-embedded normal human colon tissue*, performed on a Leica BOND. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab194109 at 1/500 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative 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.

Western blot - HRP Anti-Lamin B1 antibody [EPR8985(B)] - Nuclear Loading Control (AB194109)

ab194109 was shown to specifically react with Lamin B1 in wild-type HAP1 cells as signal was lost in LMNB1 (Lamin B1) knockout cells. Wild-type and LMNB1 (Lamin B1) knockout samples were subjected to SDS-PAGE. ab194109 and ab184095 (Mouse monoclonal [mAbcam 9484] to GAPDH - Loading Control (Alexa Fluor^® 680) loading control) were incubated overnight at 4°C at 1/5000 dilution and 1/20000 dilution respectively. The loading control was imaged using the Licor Odyssey CLx prior to blots being developed with ECL technique.

Western blot - HRP Anti-Lamin B1 antibody [EPR8985(B)] - Nuclear Loading Control (AB194109)

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab194109 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
