ab3200 at a dilution of 1/1000, staining L1CAM (green; Alexa 488 secondary at 1/2000) on 30µm coronal rat brain tissue sections in free floating IHC (see protocol link for detailed description). Images showing neuron body, cytoplasm and axon labeling: [A] neuron; 40x objective [B] neuron and axons; 40x objective and [C] punctate cytoplasmic labeling. Images coloured in Photoshop.NB: No labeling observed following omission of primary antibody.Sections were viewed using an Axioplan 2 Imaging microscope (Imaging Associates) fitted with 10x, 20x and 40x Plan-Neofluorobjectives (Zeiss, Germany) and images were taken using a AxioCam Hrm digital camera (Zeiss, Germany) and AxioVision software (Imaging Associates).
Anti-L1CAM antibody [UJ127] (ab3200) at 1 µg/ml + Brain (Human) Tissue Lysate - adult normal tissue (ab29466) at 10 µgSecondaryGoat Anti-Mouse IgG H&L (HRP) preadsorbed (ab97040) at 1/5000 dilutiondeveloped using the ECL techniquePerformed under reducing conditions.Observed band size : 230 kDa (why is the actual band size different from the predicted?)Additional bands at : 75 kDa. We are unsure as to the identity of these extra bands.Exposure time : 8 minutes L1CAM contains an exstensive number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
ab3200 staining L1CAM in human cancer cells in mouse lung tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1% BSA for 1 hour at 25°C; antigen retrieval was by heat mediation in a citrate buffer, pH 6. Samples were incubated with primary antibody (1/100 in PBS + 1% BSA) for 2 hours at 25°C. A Biotin-conjugated goat anti-mouse IgG polyclonal (1/1000) was used as the secondary antibody.See Abreview
