Western blot - Anti-CNPase antibody [11-5B] (AB6319)

Lanes 1 - 3 : Merged signal (red and green). Green - ab6319 observed at 48 kDa. Red - loading control, ab181602, observed at 37 kDa.

ab6319 was shown to recognize CNPase in wild-type HAP1 cells as signal was lost at the expected MW in CNPase knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and CNPase knockout samples were subjected to SDS-PAGE. ab6319 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at 5 μg/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye^® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye^® 680RD) preabsorbed ab216777 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CNPase antibody [11-5B] (AB6319)

IHC image of CNPase staining in human cerebral cortex 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 ab6319, 5μg/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.

ab6319 staining CNPase in the rat oligodendrocytes by ICC/IF (Immunoytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with methanol and blocked with 5% BSA for 1 hour at 37°C. Samples were incubated with primary antibody (1/100 in PBS) for 18 hours at 4°C. An Alexa Fluor^® 594-conjugated Goat anti-mouse IgG polyclonal (1 : 200) was used as the secondary antibody.

Immunocytochemistry/ Immunofluorescence - Anti-CNPase antibody [11-5B] (AB6319)

ab6319 staining CNPase in primary hippocampal rat neurons/glia, (obtained from Neuromics, cat. no. PC35101), DIV14. cells. The cells were fixed with 100% methanol (5 min), 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 ab6319 at 1μg/ml and ab6046, Rabbit polyclonal to beta Tubulin - Loading Control. Cells were then incubated with ab150117, Goat polyclonal Secondary Antibody to Mouse IgG H&L (Alexa Fluor^® 488) preadsorbed 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 pseudocolour red). Nuclear DNA was labelled with DAPI (shown in blue).

Also suitable in cells fixed with 4% paraformaldehyde (10 min).

Image was acquired with a confocal microscope (Leica-Microsystems TCS SP8) and a single confocal section is shown.
