ab24345 staining L1CAM in undifferentiated Neuro-2A cells (top panel) and TRA-differentiated Neuro-2A cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1%PBS-Tween 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 ab24345 at 5μg/ml and ab6046, Rabbit polyclonal to beta Tubulin - Loading Control, at 1/1000 dilution. Cells were then incubated with ab150117, Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) at 1/1000 dilution (shown in green) and ab150084, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 594) at 1/1000 dilution (shown in pseudocolor red). Nuclear DNA was labelled with DAPI (shown in blue).

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

This image was generated using the ascites version of the product.

IHC image of L1CAM staining in a section of formalin-fixed paraffin-embedded normal rat kidney performed on a Leica BOND^TM 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 20mins. The section was then incubated with ab24345, 0.5ug/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. 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.

All lanes :

Lane 1 : Mouse whole brain tissue lysate
Lane 2 : Rat whole brain tissue lysate
Lane 3 : Human whole brain tissue lysate

Lysates/proteins at 20 µg per lane.

Performed under reducing conditions.

Observed band size: 200 kDa why is the actual band size different from the predicted?
Additional bands at: 60 kDa (possible cleavage fragment)

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 55 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 ab24345 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at a 1ug/ml concentration and 1/10000 dilution respectively. Antibody binding was detected using Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) at 1/20000 dilution for 1 hour at room temperature before imaging.

IHC image of L1CAM staining in a section of formalin-fixed paraffin-embedded normal human kidney* performed on a Leica BOND^TM 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 20mins. The section was then incubated with ab24345, 0.1ug/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. The inset secondary-only control image is taken from an identical assay without primary antibody.

Anti-L1CAM antibody [2C2] (ab24345) at 1/1000 dilution + 30ug CNS protein

Performed under reducing conditions.

Observed band size: 200 kDa why is the actual band size different from the predicted?
Additional bands at: 60-80 kDa (possible cleavage fragment)

ab24345 recognizes one or two polypeptides of L1 or Ng-CAM corresponding to the full length protein (~200kDa) as well as 60-80 kDa  C-terminal cleavage products (as shown in the figure).

Immunofluorescence analysis of COS7 cells transfected with full-length L1CAM (left) or truncated L1CAM (right), staining L1CAM (green) with ab24345.

Cells were incubated with primary antibody (1/1000 in 1% goat serum + 0.3% Triton X-100 in PBS) and incubated overnight at 4°C. An AlexaFluor®488-conjugated anti-mouse IgG (1/700) was used as the secondary antibody. Nuclei were counterstained with bisbenzimide (blue).
